Title (EN) MODIFICATION TO STAMPABLE FLOWFIELDS TO IMPROVE FLOW DISTRIBUTION IN THE CHANNELS OF PEM FUEL CELLS
(FR) MODIFICATION POUR CHAMPS D'ÉCOULEMENT APTES À ÊTRE EMBOUTIS POUR AMÉLIORER LA DISTRIBUTION DE L'ÉCOULEMENT DANS LES CANAUX DE PILES À COMBUSTIBLE À MEMBRANE ÉCHANGEUSE DE PROTONS
Abstract: front page image
(EN)A fuel cell (10) device includes a plurality of channels (32, 34) that have at least one unrestricted inlet (33), a conduit for directing a flow having a distribution pattern (84) to the unrestricted inlet (33) and an opening (40) between the conduit (50) and the opening (40) for receiving the flow distribution pattern (84), the opening having such dimension (L, W) in which the distribution pattern tends to normalize within the opening so that flow to each of the unrestricted inlet (33) tends to normalize across said opening.
(FR)Cette invention concerne un dispositif de pile à combustible (10) comprenant une pluralité de canaux (32, 34) présentant au moins une entrée non restreinte (33), un conduit pour diriger un écoulement présentant un motif de distribution (84) vers l'entrée non restreinte (33) et une ouverture (40) entre le conduit (50) et l'ouverture (40) pour recevoir le motif de distribution d'écoulement (84). L'ouverture a des dimensions telles (L, l) que le motif de distribution tend à se normaliser au sein de l'ouverture de telle façon que l'écoulement vers chacune des entrées non restreintes (33) tend à se normaliser à travers ladite ouverture.
