Dihydrogen (H2): Production by Water Electrolysis, Molecular Storage and Conversion in a Fuel Cell
Abstract
Dihydrogen: production by water electrolysis, molecular storage and conversion in a fuel cell. The production of dihydrogen (H2) by water electrolysis, its molecular storage and its use in fuel cells are strong research topics at ISCR, requiring complementary expertises in electrochemistry, molecular chemistry and materials chemistry. This know-how has been applied to elaborate and optimise structured catalytic electrode materials based on transition metals, primarily Ni, Mo and their derivatives, for the alkaline electrolysis of water at room temperature or near-room temperature. Innovative electrode materials are also being developed to convert this molecule into electricity in solid oxide fuel cells (SOFC), which have the advantage of operating at lower temperatures and for longer periods compared to conventional fuel cells. In addition to this work, the ISCR is also investigating the storage of H2 in small organic molecules that are liquid at room temperature, such as formic acid. Using ad-hoc organometallic catalysts, these small molecules can be efficiently dehydrogenated.
