  • Publication number: 20130273446
    Abstract: An electrode comprises an acid treated, cathodically cycled carbon-comprising film or body. The carbon consists of single walled nanotubes (SWNTs), pyrolytic graphite, microcrystalline graphitic, any carbon that consists of more than 99% sp2 hybridized carbons, or any combination thereof. The electrode can be used in an electrochemical device functioning as an electrolyser for evolution of hydrogen or as a fuel cell for oxidation of hydrogen. The electrochemical device can be coupled as a secondary energy generator into a system with a primary energy generator that naturally undergoes generation fluctuations. During periods of high energy output, the primary source can power the electrochemical device to store energy as hydrogen, which can be consumed to generate electricity as the secondary source during low energy output by the primary source. Solar cells, wind turbines and water turbines can act as the primary energy source.

  • Patent number: 8404090
    Abstract: A multi-layer cathode block (30) for an electrolytic cell (10) has at least a surface layer (32) with a surface expansion index and a second layer (34) with a second expansion index. The surface layer (32) includes a surface wetting agent in a first total amount. The second layer (34) includes a wetting agent in a second total amount. The surface layer (32) is directly superposed to the second layer (34). The second wetting agent in the second layer (34) includes metal boride precursors that react together to generate a metal boride component in situ when the cathode block (30) is exposed to start-up and operation conditions of the electrolytic cell (10). The second total amount is lower than the first total amount and is selected so as to minimize the difference between the expansion indexes of the surface layer (32) and the second layer (34).
