発明の名称 (英語) Electric power generation method using electrode catalyst for fuel cell
発明の概要(英語) (US20170271686)
To provide an economical fuel cell electrode catalyst which can be used in place of platinum as a simple substance or a platinum alloy and has easy-to-control catalytic power, a molecular metal complex is used as a fuel cell electrode catalyst which molecular metal complex is a mononuclear or multinuclear coordination compound that has a particular structure, that is not a polymer compound, and that does not have a layered structure.
