Abstract
There is provided a dendritic catalyst layer for a solid polymer electrolyte fuel cell including: a solid polymer electrolyte membrane; electrodes; and catalyst layers each provided between the solid polymer electrolyte membrane and the respective electrode, the catalyst layer for a solid polymer electrolyte fuel cell includes a catalyst with a dendritic structure. The catalyst with a dendritic structure is formed through vacuum evaporation such as reactive sputtering, reactive electron beam evaporation, or ion plating. The catalyst layer for a solid polymer electrolyte fuel cell can improve catalytic activity, catalyst utilization, and substance transport performance in the catalyst layer.
