The fuel cell comprises: a receptacle (51) configured to receive a cartridge (42) for generating dihydrogen; an assembly (19) comprising a unit cell (1) comprising a cathode and an anode (3) separated by an electrolyte, where the anode surrounds the receptacle; and a unit to concentrate a heat produced by the assembly towards the receptacle. An external envelope of a stack is configured to reflect infra-red radiations resulting from the operation of the fuel cell in a direction of the receptacle. The assembly forms a hollow cylinder.

An external envelope of a stack is configured to reflect infra-red radiations resulting from the operation of the fuel cell in a direction of the receptacle. The assembly forms a hollow cylinder. The fuel cell further comprises a dihydrogen diffuser placed between the receptacle and the assembly to allow the supply of dihydrogen from the cartridge to the anode. The diffuser conducts heat. The diffuser comprises an array of grooves for guiding the dihydrogen to the assembly on a peripheral surface located opposite to a portion of the assembly. The external envelope thermally insulates the assembly from an outside of the fuel cell and passes the oxygen from the outside of the fuel cell to the cathode. |
