Solicitante:

PANASONIC IP MAN CO LTD [JP]

Resumen de: US2019379072A1

A fuel cell system includes a fuel cell, a regenerator, an oxidant feed path, a gas discharge path, and a heat exchanger. The fuel cell includes an anode and a cathode and reduces a mediator with the cathode. The regenerator oxidizes, with an oxidant, the mediator reduced by the cathode. Through the oxidant feed path, the oxidant is guided to the regenerator. Through the gas discharge path, the gas present inside the regenerator is guided out of the regenerator. The heat exchanger heats the oxidant by exchanging heat between the oxidant flowing in the oxidant feed path and the gas flowing in the gas discharge path.
