CATALYST, ELECTRODE, FUEL CELL, GAS DETOXIFICATION APPARATUS, AND METHODS FOR PRODUCING CATALYST AND ELECTRODE

摘要

Provided are a catalyst, an electrode, a fuel cell, a gas detoxification apparatus, and the like that can promote a general electrochemical reaction causing gas decomposition or the like. A catalyst according to the present invention is used for promoting an electrochemical reaction and is chain particles 3 formed of an alloy particles containing nickel (Ni) and at least one selected from the group consisting of iron (Fe), cobalt (Co), chromium (Cr), tungsten (W), and copper (Cu).
