Abstract[English]
Disclosed herein are aspects of methods, devices, and systems to control coolant delivery in a fuel cell stack. The cathode inlets on the bipolar plates disclosed herein have variable water pathways configured to deliver even quantities of water across a cathode flow field in each fuel cell forming the stack.[French]
L'invention divulgue des aspects de procédés, de dispositifs et de systèmes pour réguler la distribution de liquide de refroidissement dans un empilement de piles à combustible. Les entrées cathodiques sur les plaques bipolaires ici divulguées présentent des passages d'eau variables conçus pour distribuer des quantités d'eau homogènes à travers un champ d'écoulement cathodique dans chaque pile à combustible formant l'empilement.
