SYSTEM FOR COOLING A FUEL CELL AND FUEL CELL EQUIPPED WITH SUCH A SYSTEM

The invention relates to a system for cooling a fuel cell () of a transport vehicle such as an aircraft, comprising: a cooling heat exchanger () configured to be able to exchange heat between a loop () for cooling the cell and a channel for circulating dynamic air; a device () for recovering water produced by said fuel cell; a tank () for storing recovered water; a device () for spraying water into said dynamic air channel () upstream of said heat exchanger (); and a computer () for controlling the amount of sprayed water on the basis of a measurement representing the temperature of said fuel cell ().
