| 20100330834 | ELECTRICAL CONTACT DEVICE - An electrical contact device for an arrangement includes two apparatuses, between which a relative movement takes place along a first movement path. In at least one embodiment, the electrical contact device includes a first contact, including a first contact surface, and includes a second contact including a first multiplicity of contact arms, each provided with a contact projection for making contact with the first contact surface. In at least one embodiment, in order to prevent excessive friction wear to the first contacts even when the contact projections of the associated second contacts are arranged successively in the same direction as the first movement path, at least one device is provided for controlling a relative movement between the two contacts along a second movement path, which runs parallel to the first contact surface of the first contact and obliquely with respect to the first movement path. | 12-30-2010 |

| 20090029203 | Fuel Cell System With an Electrochemical Hydrogen Generation Cell - A system for supplying a consuming appliance with electric energy, including at least one fuel supply unit in the form of a gas evolution cell which liberates a gaseous fuel on passage of an electric current and at least one fuel cell unit in which the gaseous fuel liberated can be reacted with an oxidant to generate electric power. | 01-29-2009 |
| 20100119903 | FUEL CELL STACK WITH A LIGHTWEIGHT CONSTRUCTION - The invention relates to a fuel cell stack composed of at least one fuel cell ( | 05-13-2010 |
| 20110070480 | THREE-DIMENSIONAL MICROBATTERY AND METHOD FOR THE PRODUCTION THEREOF - A three-dimensional microbattery is disclosed, in which a depression, in which two chambers lying adjacent to one another in the substrate plane are implemented, is provided in a substrate. The active mass, which is impregnated with an electrolyte, of negative and positive electrodes is received in each of the chambers. A porous partition wall, which is impregnated with the electrolyte and prevents a passage of active electrode mass, is located between the two chambers. The free surfaces of the active mass of both electrodes and the partition wall lie in a plane with the surface of the substrate. The electrodes and the partition wall are hermetically sealed by a cover layer, which projects beyond the edge of the depression. | 03-24-2011 |
| 20110086260 | THIN HOUSING FILM FOR ELECTROCHEMICAL ELEMENTS - A housing film for electrochemical elements includes a barrier layer having a polymeric structure which has been deposited from the gas phase on to a support layer, an electrochemical element which has at least one positive electrode and at least one negative electrode and has at least one such film. A process for producing the electrochemical element includes steps wherein at least two electrodes are applied next to one another on a substrate and are covered with a film, where the substrate and/or the film is such a housing film. | 04-14-2011 |
