    摘要： A fuel cell system (200) and a method (900) for controlling temperature of a heat transfer fluid in a fuel cell system (200). The system (200) comprising at least one fuel cell stack (205) comprising at least one fuel cell, and having an anode inlet, an anode off-gas outlet for flow of anode off-gas. The system (200) further comprising a first heat exchanger (215) coupled to receive the anode off-gas which has been output form the anode off-gas outlet, the first heat exchanger (215) configured to exchange heat between the anode off-gas and a heat transfer fluid to cool the anode off-gas and heat the heat transfer fluid. The system (200) further comprising a second heat exchanger (230) that is configured to provide heat to the heat transfer fluid and a heat removal region (235) that is configured to remove heat from the heat transfer fluid. The system (200) further comprising a pump (240) configured to pump the heat transfer fluid around a fluid circuit (225) in a flow direction of: heat removal region (235) where thermal energy is removed, second heat exchanger (230) where thermal energy is added, first heat exchanger (215) where thermal energy is added. The method (900) comprises controlling (920, 945) the pump speed and controlling (925, 940) a mass flow rate of a medium to control the rate of heat removal in the heat removal region (235).
