<P>PROBLEM TO BE SOLVED: To provide an electrode catalyst layer inclining the concentration of catalyst-carried carbon particles or proton conductive substance and size of pores in the thickness direction of the electrode catalyst layer, to provide the manufacturing method of the electrode catalyst layer and a fuel cell using the electrode catalyst layer. <P>SOLUTION: The magnetic susceptibility difference is increased by dissolving at least one substance having magnetic susceptibility different from catalyst carried carbon in catalyst ink, and the catalyst carried carbon particles or a polymer electrolyte is moved in the surface direction to a polymer electrolyte membrane by inclined magnetic force. <P>COPYRIGHT: (C)2008,JPO&INPIT |
