Fuel cell system for generating electrical energy has polymer electrolyte fuel cells fed with hydrogenous fuel gas and oxidative gas and moistened by a fuel gas humidifier.

摘要

A fuel cell system (20) has a polymer electrolyte fuel cell (30) generating electrical energy if fed with a fuel gas and an oxidative gas. A fuel gas feeder (22) supplies hydrogenous fuel gas to the fuel cell. A fuel gas humidifier (23) moistens the fuel gas. An oxidative gas feeder (24) supplies an oxygenated oxidative gas like air. A cooler (50) cools the fuel cell. An electronic controller (60) regulates the operation of the fuel cell system.
