Title:
OPERATION OF A FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/174301
Kind Code:
A3
Abstract:
A liquid electrolyte fuel cell system comprises at least one fuel cell (80) comprising a liquid electrolyte chamber (82) between an anode (83) and an opposed cathode (84). During operation of the fuel cell system, ageing of the cathode is counteracted by (a) increasing the flow rate of gas to the cathode (84) during the course of operation; and/or (b) decreasing the concentration of electrolyte supplied to the liquid electrolyte chamber (82) during the course of operation. The optimum effect is achieved by performing both changes.
