  • Patent number: 8715869
    Abstract: A fuel cell, a method for operating a fuel cell and a fuel cell system, which ensure no dew condensation for a wet reaction gas in the inlet area of gas channels in plates in a fuel cell stack, are provided. Gas channels 2 and heat medium channels are disposed on one surface and the other surface of one plate 1, respectively.
