Title
(EN) HYDROPHILIC SURFACE MODIFICATION OF BIPOLAR PLATE
(FR) MODIFICATION SUPERFICIELLE HYDROPHILE D'UNE PLAQUE BIPOLAIRE HYDROPHILIC SURFACE MODIFICATION OF BIPOLAR PLATE
Abstract
(EN) A bipolar plate (32) having hydrophilic surfaces (48) is disclosed. The bipolar plate includes multiple surfaces including channels (34) having channel surfaces (35). A hydrophilic coating is provided on the surfaces to enhance the water management capabilities of a fuel cell.
(FR) L'invention concerne une plaque bipolaire présentant des surfaces hydrophiles. La plaque bipolaire comprend de multiples surfaces munies de canaux présentant des surfaces de canaux. Un revêtement hydrophile est ménagé sur les surfaces pour améliorer les capacités de régularisation des eaux d'une pile à combustible.
