PURPOSE:To provide a fuel cell excellent in the initial characteristics and secular stability by structuring a catalyst so that a ternary alloy of platinum, vanadium, and chromium is borne by a carrier consisting of carbon, and fastening the catalyst onto an electrode base material using a binder. CONSTITUTION:A catalyst 3 is structured so that a ternary alloy 2A consisting of 10-30% vanadium, 10-30% chromium, and platinum for remainder is borne by a carrier of carbon. An electrode catalyst layer 5 is formed by fastening this catalyst 3 onto an electrode base material 1 using a binder. This ternary alloy catalyst has a small dia. of crystallite and presents lesser secular change. This achieves a fuel cell excellent in the initial characteristics and secular stability. |
