ELECTRODE FOR A FUEL CELL AND FUEL CELL

摘要

The invention relates to a fuel cell comprising two electrodes of differing polarity and an electrolyte arranged between them, and to an electrode for fuel cells constructed in this way. Said electrode comprises pores which a fluid, especially a gas, can pass through from a surface (1) on the gas side to surface (2) on the electrolyte side; and at least one contact point (3) where electrons are conducted. The electrode has at least one collective conductor (4) whose specific resistance is lower than the specific resistance of the electrode. As a result, the ohmic loss in relation to the electrode is reduced and the degree of efficiency of a fuel cell equipped with an electrode of this type is increased. The inventive fuel cells with the inventive electrodes of differing polarity can therefore be combined with an electromotor to provide an alternative to conventional internal combustion engines, especially in vehicles and rail systems.
