<P>PROBLEM TO BE SOLVED: To solve problems of deterioration of output voltage by invasion of fuel gas into an electrolyte in a conventional fuel cell and reduction of the output voltage by joining of different kinds of materials at the interface of an electrolyte and an electrode. <P>SOLUTION: By composing a membrane of which bores are closed by filling hydrophilic materials in the bores of the porous membrane as a buffer layer between the electrolyte and the electrode, water can pass although the fuel gas can not, and supply of the water to the electrolyte can be carried out and the reduction of the output voltage can be prevented by preventing diffusion of the gas to the electrolyte. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
