NOVELTY - A fuel cell consists of catalyst layers (14c,13c) respectively functioning as anode (14) and cathode (13), contacting either surfaces of a solid polymer electrolyte membrane (15). The fuel cell produces electric power using electrochemical reaction. The electrolyte membrane contacts the opposite side of catalyst layer (14c). The fuel cell consists of a hydrophilic fuel-gas distribution portion having holes used as flow path of fuel supplied to catalyst layer (14c), with liquid water (W) supplied with fuel gas being supplied to catalyst layer (14c).    USE - Fuel cell is used for forming fuel-cell stacks (claimed) used for electric-power generation in electric vehicles, outdoor installations, portable power supplies, and portable electronic devices.    ADVANTAGE - The fuel cell suppresses lack of moisture content in the anode, exhibits excellent electric-power generation performance characteristics, and has a simple structure. Liquid water is efficiently supplied to the catalyst layer. The moisture content in anode side can be controlled without requiring feedback control systems, such as impedance measurement systems.    DETAILED DESCRIPTION - A fuel cell consists of catalyst layers (14c,13c) respectively functioning as anode (14) and cathode (13), contacting either surfaces of a solid polymer electrolyte membrane (15). The fuel cell produces electric power using electrochemical reaction which produces water from fuel gas supplied to catalyst layer (14c) and oxidizing agent supplied to catalyst layer (13c). The electrolyte membrane contacts the opposite side of catalyst layer (14c). The fuel cell consists of a hydrophilic fuel-gas distribution portion having holes used as flow path of fuel supplied to catalyst layer (14c), with liquid water (W) supplied with fuel gas being supplied to catalyst layer (14c).
