Abstract
The disclosure is concerned with a fuel cell battery of an acidic electrolyte type, which comprises means for controlling the flow rate of an oxygen-containing gas, such as air, to be fed to an oxidant electrode of the fuel cell battery in a quantity to completely remove water that is formed on the oxidant electrode by the reaction between fuel and the oxidant from the oxidant electrode. The fuel cell battery prevents lowering of the battery performance due to accumulated water on the oxidant electrode. Also disclosed is means for removing the gas formed at the fuel electrode of the fuel cell from the fuel chamber.
