CA 2490669

A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first and second metal plates. The coolant flow field is connected to inlet buffers and outlet buffers. Protrusions for limiting the flow of a coolant are provided at the inlet buffers and the outlet buffers on upper and lower opposite end positions of the coolant flow field.

Une pile à carburant est formée en empilant des ensembles membrane-électrode et des séparateurs les uns par-dessus les autres, tour à tour. Chacun des séparateurs comprend une première et une deuxième plaque de métal. Un champ de circulation de refroidissement est formé entre la première et la deuxième plaque de métal. Le champ de circulation de refroidissement est branché à des tampons d'entrée et des tampons de sortie. Des saillies, qui limitent la circulation d'un refroidisseur, sont prévues aux positions d'extrémités opposées des tampons d'entrée et de sortie supérieur et inférieur.
