  • Patent number: 8337678
    Abstract: A hydrogen electrolysis apparatus includes a stack of unit cells each having a membrane electrode assembly sandwiched between an anode separator and a cathode separator. The anode separator has a first flow field which is supplied with water, and the cathode separator has a second flow field which produces high-pressure hydrogen through an electrolysis of the water. The cathode separator also has a first seal groove defined therein which extends around the second flow field and a first seal member inserted in the first seal groove. The first seal groove and the second flow field are held in fluid communication with each other through passageways. The passageways keep the first seal groove and the second flow field in direct fluid communication with each other in bypassing relation to the boundary between the cathode separator and a solid polymer electrolyte membrane.

    Abstract: An apparatus for recharging a fuel cell cartridge and methods for recharging a fuel cell cartridge are disclosed. An example recharging apparatus may include a housing having a fuel cell cartridge holder. A water reservoir may be disposed in the housing and may have water disposed therein. The recharging apparatus may also include an electrolysis chamber for converting water into hydrogen and oxygen. The electrolysis chamber may be in fluid communication with the water reservoir. The electrolysis chamber may include a hydrogen passage for passing hydrogen from the electrolysis chamber to the fuel cell cartridge holder. The recharging apparatus may further include a vacuum pump at least selectively in fluid communication with the fuel cell cartridge holder. In some instances, the vacuum pump may be used to evacuate residual hydrogen and/or other gases or materials from the fuel cell cartridge and/or determine if the fuel cell cartridge is leaky and requires replacement.

    Abstract: Electrochemical systems and methods for producing hydrogen. Generally, the systems and methods involve providing an electrochemical cell that includes an anolyte compartment holding an anode in contact with an anolyte, wherein the anolyte includes an oxidizable substance having a higher standard oxidation potential than water. The cell further comprises a catholyte compartment holding a cathode in contact with a catholyte that includes a substance that reduces to form hydrogen. Additionally, the cell includes an alkali cation conductive membrane that separates the anolyte compartment from the catholyte compartment. As an electrical potential passes between the anode and cathode, the reducible substance reduces to form hydrogen and the oxidizable substance oxidizes to form an oxidized product.
