Patent ID: 8372554

Claim:
A cooling system for cooling a fuel-cell system on board an aircraft, the fuel cell system comprising: a fuel cell; and a water condenser; wherein the cooling system comprises: a hydride accumulator integrated in the fuel cell; and a connection device coupling an external cooling system with the hydride accumulator and a coupler coupling the hydride accumulator to an external source hydrogen for charging the hydride accumulator with hydrogen; wherein the hydride accumulator is arranged such that the fuel-cell is cooled only during discharge of hydrogen from the hydride accumulator, without any external cooling of the fuel cell by the external cooling system, and the external cooling system dissipates heat which arises during charging of the hydride accumulator with hydrogen, when the external cooling system is coupled by the connection device with the hydride accumulator exclusively during charging and the external cooling system remains on the ground during flight of the aircraft.
