METHOD FOR OPERATING HIGH TEMPERATURE POLYMER ELECTROLYTE MEMBRANE FUEL CELL FOR MAXIMIZING LIFESPAN OF STACK

摘要

According to an embodiment of the present invention, a method for operating a high temperature polymer electrolyte membrane fuel cell comprises: an initial operating step including a step of conducting partial load operation at a temperature lower than a target driving temperature without heating a high temperature polymer electrolyte membrane fuel cell to the target driving temperature during an early stage of operation; and a normal operating step of conducting operation at the target driving temperature while a rated fuel supply and rated load are authorized, wherein the normal operating step is performed after the initial operating step. The operation method minimizes exposure to conditions which expedite heat deterioration of the high temperature polymer electrolyte membrane fuel cell.;COPYRIGHT KIPO 2016
