Abstract
The invention relates to a system for cooling a fuel cell (10) of a transport vehicle such as an aircraft, comprising: a cooling heat exchanger (30) configured to be able to exchange heat between a loop (20) for cooling the cell and a channel for circulating dynamic air; a device (22, 23) for recovering water produced by said fuel cell; a tank (25) for storing recovered water; a device (50) for spraying water into said dynamic air channel (40) upstream of said heat exchanger (30); and a computer (28) for controlling the amount of sprayed water on the basis of a measurement representing the temperature of said fuel cell (10).
Claims13
A system for cooling a fuel cell of a transport vehicle, which fuel cell comprises an anode and a cathode, said system comprising a cooling loop of the cell that is in thermal interaction with said anode and/or said cathode, the system comprising:
- a cooling heat exchanger configured to be able to exchange heat between said cooling loop and a dynamic air channel circulating cooling air drawn from outside the transport vehicle,
- a water recovering device of recovering water produced by said fuel cell,
- a water tank for storing water, which water tank is fluidically connected to said water recovering device in order to be able to store said recovered water therein,
- a water spraying device spraying water into said dynamic air channel upstream of said cooling heat exchanger, said spraying device being fluidically connected to said water tank,
- a computer for controlling the amount of water sprayed by said water spraying device into said dynamic air channel on the basis of a measurement representing a temperature of said fuel cell.
A fuel cell of a transport vehicle, comprising an anode equipped with an anode inlet intended to be supplied with a combustible fluid and an anode outlet intended to provide an anode product fluid, and a cathode equipped with a cathode inlet intended to be supplied with an oxidizing fluid and a cathode outlet intended to provide a cathode product fluid, wherein the fuel cell also comprises a cooling system comprising:
- a cooling heat exchanger configured to be able to exchange heat between a cooling loop and a dynamic air channel for circulating cooling air drawn from outside the transport vehicle,
- a water recovering device recovering water produced by said fuel cell,
