  • ON-DEMAND HYDROGEN GAS GENERATION DEVICE
    Publication number: 20090081501
    Abstract: The present disclosure generally relates to an on-demand hydrogen gas generation device, suitable for use in a fuel cell, which utilizes water electrolysis, and more particularly galvanic cell corrosion, and/or a chemical hydride reaction, to produce hydrogen gas. The present disclosure additionally relates to such a device that comprises a switching mechanism that has an electrical current passing therethrough and that repeatedly and reversibly moves between a first position and a second position when exposed to pressure differential resulting from hydrogen gas generation, in order to (1) alter the rate at which hydrogen gas is generated, such that hydrogen gas is generated on an as-needed basis for a fuel cell connected thereto, and/or (2) ensure a substantially constant flow of hydrogen gas is released therefrom.
    Type: Application
    Filed: July 22, 2008
    Publication date: March 26, 2009
    Applicant: ROVCAL, INC.
    Inventors: Viet Vu, Zhihong Jin, Juergen Scherer, Joseph L. Passaniti, Gregory J. Davidson, Craig Rom, Mario DeStephen, Jon Luecke, Erik Mortensen, Jamie L. Ostroha, Karthik Ramaswami, Tony Rubsam, William C. Bushong
