摘要： The present invention provides a fuel electrode of a solid polymer electrolyte fuel cell for advancing a fuel cell reaction to oxidize the fuel introduced through a diffusion layer, comprising at least one reaction layer which is in contact with a solid polymer electrolyte membrane and advances the fuel cell reaction and at least one water decomposition layer which is in contact with the diffusion layer and electrolyzes the water in the fuel electrode. The layer taking charge of the fuel cell reaction is protected by providing the fuel electrode having a multilayer structure and providing the layer for preferentially performing the electrolysis of the water contained in the fuel or the like. This results in a fuel electrode in which the reduction of the electrode performance will not easily occur even when fuel shortage may be created.
