ABSTRACT:
A solid polymer fuel cell includes an electrode-electrolyte membrane coupling structure3configured to generate electric power through a chemical reaction between a fuel aqueous solution and an oxidant; a hydrophilic membrane17made of a hydrophilic material; and a repellent porous membrane18made of a repellent material. The repellent porous membrane18is arranged between the electrode-electrolyte membrane coupling structure3and the hydrophilic membrane17. The fuel aqueous solution is supplied through the hydrophilic membrane17and the repellent porous membrane18to the electrode-electrolyte membrane coupling structure3. At this time, the solid polymer fuel cell10can prevent the fuel from being excessively permeated, even though using the fuel aqueous solution of the high concentration. Also, the solid polymer fuel cell can prevent a lack of the water on the anode6and the increase in the crossover of the fuel to the cathode7, and can suppress the property deterioration and can obtain the sufficient electric generation property.
