  • Method for fabricating a fuel cell on a porous support
    Patent number: 7976895
    Abstract: To prevent the liquid electrolyte from penetrating into the porous support while at the same time preserving or increasing the power density of the fuel cell, before the liquid electrolyte is deposited, at least a part of the walls delineating the pores of said support is covered by a film formed by a material presenting a contact angle of more than 90° with a drop of said liquid electrolyte. Said film further presents a thickness enabling passage of the reactive fluid in the pores of the support.
    Type: Grant
    Filed: July 7, 2008
    Date of Patent: July 12, 2011
    Assignee: Commissariat a l 'Energie Atomique
    Inventors: Vincent Faucheux, Christelle Laugier, Jean-Yves Laurent, Steve Martin
  • WATER MANAGEMENT IN A FUEL CELL
    Publication number: 20100183954
    Abstract: A hydrogen-oxygen fuel cell including, on the anode side, a hydrogen storage buffer chamber. The buffer chamber includes a wall having at least a semi-permeable portion, impermeable to gases (hydrogen-oxygen-air) and permeable to water.
