Abstract
Provided is a fuel cell having a membrane electrode assembly for generating power by oxidizing fuel at an anode electrode and reducing oxygen at a cathode electrode, an anode diffusion layer for allowing fuel to pass therethrough to the outside of the anode electrode of the membrane electrode assembly and transferring electrons generated by the oxidation, a cathode diffusion layer for removing water thus generated and transferring electrons to be used for the reduction to the outside of the cathode electrode, an anode current collector and anode endplate for transferring electrons generated by the oxidation to the outside of the anode diffusion layer, and a cathode current collector and a cathode endplate for transferring electrons to be used for the reduction to the outside of the cathode diffusion layer. The anode endplate or anode current collecting layer is hydrophilic or the end plate on the anode side has a constitution promoting discharge of a gas generated by the reaction.
