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.

A catalyst for a fuel cell containing polymer solid electrolyte, which catalyst contains platinum/ruthenium on a carrier in proportions of 2-4:8-6 on a mol basis and exhibits excellent resistance to catalyst poisoning attributed to carbon monoxide. In the present invention, there is disclosed a method for producing the catalyst, which-includes adding an alcohol to a mixture of an aqueous solution of a ruthenium compound and a platinum catalyst, reducing ruthenium, and causing ruthenium to precipitate at a reaction temperature between 60° C. and the boiling point of the mixture after addition of alcohol. A suitable alcohol may be ethanol or methanol in the concentration of 5-15 vol. % based on the total volume of the mixture, and a suitable heating temperature is in the vicinity of the boiling point of the mixture to which ethanol or methanol has been added. According to the present method, there can be produced a platinum/ruthenium catalyst for a fuel cell containing polymer solid electrolyte, which catalyst contains platinum particles and ruthenium particles in proximity to one another on a carrier without causing aggregation and exhibits excellent resistance to catalyst poisoning attributed to carbon monoxide.
