Abstract
There are provided an electrocatalyst having an excellent poisoning resistance to carbon monoxide for use in solid polymer electrolyte fuel cells, an electrode, a membrane-electrode assembly, and a solid polymer electrolyte fuel cell, using said electrocatalyst. The electrocatalyst is comprised of a cubic platinum-ruthenium solid solution alloy and a hexagonal ruthenium supported together on a conductive carbon carrier.
