Title:
FUEL-CELL SYSTEM AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2014/091851
Kind Code:
A1
Abstract:
This fuel-cell system, in which fuel cells generate electricity by electrochemically reacting a cathode gas supplied to cathodes with an anode gas supplied to anodes, is provided with a cooling system that supplies cooling water to the anodes via separators. Said fuel-cell system contains the following: a fuel-gas supply unit that supplies the anode gas to the anodes of the fuel cells at a prescribed pulsating pressure on the basis of a required electricity-generation amount; a cooling-water supply unit that supplies the cooling water at a prescribed flow rate on the basis of either how wet electrolyte membranes in the fuel cells are or the heat-dissipation demands of the fuel cells; and a control unit that controls the flow rate of the cooling water and/or the pulsating pressure of the anode gas such that the pressure of the cooling water inside the fuel-cell stack falls outside the range over which the pulsating pressure varies.
