20080226967BIFURCATION OF FLOW CHANNELS IN BIPOLAR PLATE FLOWFIELDS - A bipolar plate for a fuel cell is provided that includes a flowfield having an active surface with an inlet region and an outlet region. The active surface of the flowfield is in communication with the inlet region and the outlet region and has at least one flow channel formed therein. The at least one flow channel further has a cross-sectional area at the outlet region that is less than a cross-sectional area at the inlet region. In particular embodiments, the at least one flow channel is bifurcated. A fuel cell stack including a fuel cell and the bipolar plate is also provided.09-18-2008
20080311437METHOD FOR FUEL CELL START-UP WITH UNIFORM HYDROGEN FLOW - A fuel cell system is provided having a fuel cell stack including a plurality of fuel cells. The fuel cell system includes an anode supply manifold in fluid communication with the plurality of fuel cells, the anode supply manifold adapted to deliver a anode supply stream to the plurality of fuel cells; an anode exhaust manifold in fluid communication with the anodes of the plurality of fuel cells, the anode exhaust manifold adapted to receive an anode exhaust stream from the plurality of fuel cells; a first valve in fluid communication with the anode supply manifold; and a second valve in fluid communication with the anode exhaust manifold. A method of starting the fuel cell system is also provided. The fuel cell system and method militates against a non-uniform distribution of the anode supply stream to the anodes of the plurality of fuel cells.12-18-2008
20090269637FUEL CELL MODULE DESIGN FOR ROBUST PRESSURE MEASUREMENTS IN FREEZING CONDITIONS - A fuel cell system is disclosed including a fuel cell stack and pressure sensors, wherein bypass conduits having flow restriction devices disposed therein are provided for bypassing fluids around the fuel cell stack to militate against the accumulation of moisture in conduits in fluid communication with the pressure sensors.10-29-2009

20110223513PEM FUEL CELL STACK HYDROGEN DISTRIBUTION INSERT - A fluid distribution insert adapted to be received within an inlet header of a fuel cell assembly. The fluid distribution insert includes a hollow insert with a first end and a second end. An inlet is formed at the first end of the hollow insert in fluid communication with a source of a reactant gas and adapted to receive the reactant gas therein. An outlet is formed intermediate the first end and the second end. The outlet is adapted to deliver the reactant gas to a plurality of fuel cells of the fuel cell assembly, wherein the hollow insert delivers the reactant gas to the fuel cells in a substantially simultaneous and uniform manner.09-15-2011

20100274596PERFORMANCE DASHBOARD MONITORING FOR THE KNOWLEDGE MANAGEMENT SYSTEM - Embodiments of the present invention provide a method, system, computer program product, or a combination of the foregoing for creating a knowledge management system including a performance dashboard monitoring system that is standardized and centralized across the channels and sub-channels in an organization. The performance dashboard monitoring system is used to track, measure, and resolve incidents that occur throughout the channels, sub-channels, systems, and applications of an organization. The system receives information related to two or more incidents, where each incident is associated with one or more of a business channel, sub-channel, or application. The system stores the information on a memory device. The system tracks the status of at least one incident between the occurrence and the resolution of the incident. The system displays on a user interface the information related to the incident on a channel, sub-channel, application, or individual incident level.10-28-2010
20100274616INCIDENT COMMUNICATION INTERFACE FOR THE KNOWLEDGE MANAGEMENT SYSTEM - Embodiments of the present invention include a method, system, computer program product, or a combination of the foregoing for creating a knowledge management system with an incident communication interface for production support incidents that is standardized and centralized across the channels and sub-channels in an organization. The incident communication interface system is used to track, identify, and resolve the incidents that occur throughout the organization. The incident communication interface allows business associates to initiate an incident ticket associated with an incident. The incident communication interface also communicates information related to an incident to business associates. The incident communication interface provides the business associates knowledge management system access. The incident communication interface receives user input including details related to resolving the incident and the incident details are stored in the incident report database.10-28-2010
20100274789OPERATIONAL RELIABILITY INDEX FOR THE KNOWLEDGE MANAGEMENT SYSTEM - Embodiments of the present invention provide systems, methods, and computer program products for an operational reliability index (“ORI”) scoring system in the knowledge management system that is standardized and centralized across the channels and sub-channels in an organization. The ORI system scores the reliability or confidence of the channels, sub-channels, and applications in an organization. The ORI receives reliability data associated with one or more predictability factors related to a business application. The ORI determines predictability factor reliability scores for each of the one or more predictability factors based on the reliability data and weighted values assigned to the predictability factors. Weighted values are also assigned to the categories, applications, sub-channels, and channels. The ORI determines at least one of a category reliability score, application reliability score, business sub-channel reliability score, or business channel score based on the determined predictability factor reliability scores and the weighted values.10-28-2010
20100274814ACADEMY FOR THE KNOWLEDGE MANAGEMENT SYSTEM - Embodiments of the present invention provide a method, system, computer program product, or a combination of the foregoing for creating a knowledge management system including an academy system for training and tracking training results of employees in a standardized and centralized location across the channels and sub-channels in an organization. The academy system stores a plurality of training modules, associated with one or more certification programs. The academy system further provides a user training selection interface configured to provide for user selection of one or more of the plurality of training modules. The academy system further provides the user access to the selected training module through an interactive display module interface. The academy system further provides for a user training results interface configured to provide a display of the user training results and stores the user training results of the selected training module in a user training database.10-28-2010
20100275054KNOWLEDGE MANAGEMENT SYSTEM - Embodiments of the present invention address the above needs and/or achieve other advantages by providing a method, system, computer program product, or a combination of the foregoing for creating a knowledge management system for production support that is standardized and centralized across the channels and sub-channels in an organization. The knowledge management system receives information relating to incidents from databases in the organization. The knowledge management system displays via a user interface at least the following information related to at least one incident, the current status of the incident, the recovery guidelines for effecting resolution of the incident, and scoring values associated with the incident. The knowledge management system also stores and displays historical information, contact information, incident reports, and outstanding incident tickets associated with the incident, as well as process maps or flowcharts for systems, applications, and customer views, and an academy for training associates.10-28-2010
