Nuclear Production of Hydrogen
Third Information Exchange Meeting, Oarai, Japan, 5-7 October 2005
Hydrogen has the potential to play an important role as a sustainable and environmentally acceptable energy carrier in the 21st century. Since natural sources of pure hydrogen are extremely limited, it is necessary to develop technologies to produce large quantities of hydrogen economically. The currently dominant technology for producing hydrogen is based on reforming fossil fuels, a process which releases greenhouse gases. Hydrogen produced by water cracking, using heat and surplus electricity from nuclear power plants, requires no fossil fuels and results in lower greenhouse gas emissions. This conference proceedings presents the state of the art in the nuclear production of hydrogen and describes its associated scientific and technical challenges.

Direct Energy Conversion by Proton-Conducting Ceramic Fuel Cell Supplied with CH4 and H2O at 600-800°C
Nuclear Energy Agency
Relations between current density and terminal voltage (I-V curves) of the proton-conducting ceramic of SrCe0.95Yb0.05O3-a were determined for application to a fuel cell working at 600 - 800°C. In a similar way to the introduction of a H2 + H2O mixture, its anode supplied with a CH4 + H2O mixture worked as a fuel cell efficiently without any external CH4-to-H2 reformer.
