20130071769 | FUEL CELL - Disclosed is a fuel cell provided with a membrane electrode structure having a frame, two separators that sandwich the membrane electrode structure therebetween, and gas seals between the end portion of the frame and the end portions of respective separators, and diffuser sections for distributing a reacting gas to between the frame and respective separators. In the diffuser section on the cathode side, the frame is provided with a protruding section in contact with the separator, and in the diffuser section on the anode side, the frame and the separator are disposed by being spaced apart from each other, thereby excellently maintaining contact surface pressure between the membrane electrode structure and the separators, and preventing contact resistance from being increased. | 03-21-2013 |
20130115541 | FUEL CELL - A fuel cell is provided with a membrane electrode assembly provided with a frame, both of which are sandwiched between two separators. The fuel cell is configured such that reactive gas is circulated between the frame and the separators. The frame and both separators each have manifold holes, the rims of the manifold holes of frame extend into the manifold holes in the separators, and protrusions cover the inner peripheral surfaces of the manifold holes in at least one of the separators. This structure makes possible the easy and accurate position and integration of the separators and the frame, and fuel cell miniaturization can be achieved because space to position the protrusions is not needed. | 05-09-2013 |

20140011110 | FUEL BATTERY CELL - A fuel battery cell C includes a membrane electrode assembly | 01-09-2014 |
20140017593 | FUEL BATTERY CELL - A fuel battery cell includes: a membrane electrode assembly having a resin frame in a periphery of the membrane electrode assembly; two separators holding the frame and the membrane electrode assembly between the two separators; and diffuser areas each provided between the frame and each of the separators and allowing a reaction gas to flowthrough the diffuser areas. In the diffuser area on any one of a cathode side or an anode side, at least one of mutually opposed surfaces of the frame and the separator is provided with a protruding portion in contact with the other opposed surface. In the diffuser area on the other side, a displacement in a thickness direction between the frame and the separator is capable of being absorbed. | 01-16-2014 |

20150037702 | VEHICLE-MOUNTED CELL STACK SYSTEM - A vehicle-mounted cell stack system includes a cell stack that comprises a plurality of laminated power generating cells, and power collecting plates that sandwich both outermost power generating cells, electric wires connected to the power collecting plates, and an electric load connected to the power collecting plates via the electric wires and configured to be activated by electric power that is supplied from the cell stack. The electric wires are connected to the power collecting plates in a direction other than a cell laminating direction. | 02-05-2015 |
20150125781 | FUEL CELL - A fuel battery cell has a membrane electrode assembly, a frame, a pair of separators, and support members. The membrane electrode assembly is formed with an anode and a cathode bonded so as to face an electrolyte membrane. The frame holds the periphery of the membrane electrode assembly. The pair of separators sandwich the frame holding the membrane electrode assembly. The support members protrude along an edge part of the frame so as to pass beyond the frame and support the membrane electrode assembly. | 05-07-2015 |
