Title (EN) FLUID FLOW ASSEMBLIES FOR, AND IN, FUEL CELL STACKS
(FR) ENSEMBLES DE CIRCULATIONS DE FLUIDE POUR, ET DANS, DES EMPILEMENTS DE PILES À COMBUSTIBLE
Abstract:
(EN) Fuel cells and related assemblies involving directionally independent channels are provided. In this regard, a representative fuel cell stack (100) includes: a first fuel cell (102) having channels (116, 216, 316; 156, 256, 356) associated with an anode; and a second fuel cell (101), located adjacent the first fuel cell, having channels (128, 228, 328; 158, 258, 358) associated with a cathode, the channels associated with the cathode exhibiting directional independence (344) with respect to the channels associated with the anode. A ribbed, three plate (111, 211, 311; 121, 221, 321; 150, 250, 350), assembly (152, 252) may provide fuel reactant and anode coolant flow channels having a first parallel orientation (342) and oxidant reactant and cathode coolant flow channels having a second parallel orientation independent of and different (344) than the first orientation.
(FR) L'invention porte sur des piles à combustible et sur des ensembles s'y rapportant impliquant des canaux directionnellement indépendants. A cet égard, un empilement de piles à combustible représentatif (100) comprend : une première pile à combustible (102) comprenant des canaux (116, 216, 316 ; 156, 256, 356) associés à une anode ; et une seconde pile à combustible (101) placée adjacente à la première pile à combustible, comprenant des canaux (128, 228, 328 ; 158, 258, 358) associés à une cathode, les canaux associés à la cathode présentant une indépendance directionnelle (344) par rapport aux canaux associés à l'anode. Un ensemble (152, 252) à trois plaques cannelées (111, 211, 311 ; 121, 221, 321 ; 150, 250, 350) peut former des canaux d'écoulement de réactif combustible et d'agent de refroidissement d'anode ayant une première orientation parallèle (342) et des canaux d'écoulement de réactif oxydant et d'agent de refroidissement de cathode ayant une seconde orientation parallèle indépendante et différente (344) de la première orientation.
