Abstract: A fuel cell system includes a fuel pre-heater, a fuel cell stack and a cooling circuit which is arranged to implement a Rankine cycle and includes a condenser. The fuel pre-heater is arranged to heat a flow of liquid hydrogen provided to an input thereof to provide a flow of gaseous hydrogen. The system further includes a conveying apparatus arranged to convey the gaseous hydrogen to a fuel input of the fuel cell stack such that the gaseous hydrogen is in thermal contact with coolant fluid in the condenser. The size and mass of the condenser may thereby be reduced. The pre-heater is arranged to heat coolant fluid within the cooling circuit, thereby increasing the efficiency of the Rankine cycle.
