Each fuel cell includes a fuel cell gas-flow passage extending lengthwise from a first end to a second end of the each fuel cell. The vaporizer is disposed near the fuel cell stack for generating the water vapor-containing gas to be supplied to the electrolysis cell stack device. At least a portion of the hydrogen-containing gas is supplied to the fuel cell stack device. | 06-09-2016 |
