Title (EN) MICROSTRUCTURED FLOW FIELDS
(FR) CHAMPS D'ECOULEMENT A MICROSTRUCTURES
Abstract: front page image
(EN)A flow field for an electrochemical cell such as a fuel cell is provided, having micro-flow channels having a width or depth of less than 800 $g(m)m, a pitch of less than 800 $g(m)m, or a proportion of inter-channel land area of less than 25 %. The channels may further comprise micro-features within the channels. A flow field plate comprising the subject flow field is provided.
(FR)La présente invention concerne un champ d'écoulement pour cellule électrochimique, par exemple pour une pile à combustible, comportant des micro-canaux d'une largeur ou d'une profondeur inférieure à 800 $g(m)m, avec un écartement inférieur à 800 $g(m)m, ou une proportion de cordons inter-canaux inférieure à 25 %. Par ailleurs, les canaux peuvent présenter des mini-caractéristiques. L'invention concerne une plaque d'écoulement de courant renfermant le champ d'écoulementn question.
