Provided is a fuel cell anode catalyst in which a platinum-ruthenium alloy is supported on a carbon material, and a manufacturing method therefor. The molar ratio (Pt:Ru) of the alloy is in the range of 1:1-5. When the coordination numbers of the Pt atom a...

Provided is a fuel cell which can obtain a sufficiently high electromotive force even under a low-temperature condition such as room temperature without using a deleterious substance or platinum. This fuel cell uses an electrolyte layer containing a layer ...
