Claim:
A feed plate of at least one fuel cell which includes: apertures for the feeding of fuel ( 3 , 30 ), oxidiser ( 2 , 20 ) and coolant fluid ( 4 , 40 , 54 , 59 ); two opposite faces ( 1 A, 1 B, 5 lA, 51 B) on at least one of which there are the circulation channels ( 21 , 22 , 61 ) for the fuel or the oxidiser, at least one refrigeration channel ( 41 , 53 ) located on the same face or faces as that with the channels for circulation of the fuel or oxidiser, so as to be coplanar with these first circulation channels, wherein the first channels for circulation respectively of the fuel ( 22 ) and the oxidiser ( 21 ) are located on both faces ( 1 A, 1 B) of the plate, with refrigeration taking place on both faces of the plate, so that the plate then constitutes a bipolar plate, with one single refrigeration channel ( 41 ) being located on both faces ( 1 A, 1 B) and, as a consequence, having several through passages ( 43 , 58 ) in the plate, from one face to the other, as well as branches, and wherein said apertures for feeding of coolant fluid ( 4 , 40 , 54 , 59 ) comprise an inlet ( 4 , 54 ) for the coolant fluid and an outlet ( 40 , 59 ) for the coolant fluid, said inlet and outlet being in fluid communication with the several through passages ( 43 , 58 ) via the refrigeration channel ( 41 ).
