| 摘要 |
The invention relates to a fuel cell, comprising a cell stack (1) having several cells (2, 2') and end plates, but without bipolar plates. In the membrane electrode unit (4), the electrolyte membrane and gas diffusion layers lie between the anode catalyst and the cathode catalyst. A cooling and media module (3, 163, 166) having the media lines for oxygen, hydrogen, and the cooling medium is designed only to provide secondary functional chambers and to form stacks. The electrical conductors are designed as current paths (81) and integrated in the cell stack (1). The cells (2, 2') are divided into one or more stack cells (87, 87') having one or more sub-cells (173, 173'). The fuel cell, which is used to generate electricity, can also be adapted to generate H2 gas and/or O2 gas from water using electricity. |
