Abstract
An airbreathing fuel cell comprising a power generating cell stack constituted by laminating a plurality of cell parts together, which cell part comprises a polymer electrolyte membrane, an oxygen electrode and a fuel electrode, which are provided on both sides of the polymer electrolyte membrane to be opposed to each other, an oxygen passage plate provided adjacent to the oxygen electrode, and separator plates provided adjacent to an outside of the oxygen passage plate and an outside of the fuel electrode, and a cell stack for removal of moisture, connected to the power generating cell stack and comprising at least one cell, which is constructed in the same manner as the cell part, and to which resistances are connected to be capable of power generation, and wherein moisture generated in the power generating cell stack due to an operation over a long period of time is conducted to the cell stack for removal of moisture together with a fuel, and removed through natural evaporation to outside and around the fuel cell, thus suppressing a decrease in power generating capacity.
