US 2014/0193726 A1 · FULL CELL SYSTEM AND METHOD OF HUMIDIFYING AND COOLING THE SAME

Abstract

A method of humidifying and cooling a fuel cell system is provided. The method of humidifying and cooling a fuel cell system includes: exhausting, by a fuel supply unit, a hydrogen gas to a reservoir in which condensed water of an anode is stored. Additionally, a hydrogen gas and condensed water are pumped and the hydrogen gas and the condensed water are exhausted to the humidifier. Additionally, compressed air of an air compressor is delivered to the humidifier heat is exchanged with compressed air in the humidifier. The hydrogen gas and compressed air in which a heat is exchanged in a humidified state is delivered to an anode and a cathode, respectively.

Dependent claims

A fuel cell system, comprising:

a stack including an anode and a cathode;
a fuel supply unit that supplies a hydrogen gas of a hydrogen tank to the anode through a hydrogen supply line;
an air supply unit that supplies compressed air of an air compressor to the cathode via a humidifier through an air supply line;
and
a reservoir that exhausts condensed water of the anode,
wherein the fuel supply unit connects the hydrogen supply line to the anode via the reservoir and the humidifier, the hydrogen gas and the compression air exhausted to the reservoir and the injected hydrogen gas and condensed water exchange a heat with compressed air in the humidifier.
