A hydrogen storage method is provided which enables a hydrogen storage alloy to store hydrogen up to a maximum hydrogen storage amount thereof in excess of a generally known theoretical value. In a hydrogenation step, a hydrogen storage ratio calculated as...

An electricity generation device (1) using a fuel cell (2) having a fuel electrode (5) and an air electrode (6) to which a fuel gas and air are supplied, respectively, includes: a fuel gas conduit (3) through which the fuel gas flows; a cover (9) configure...

An electricity generation device includes: a tubular fuel cell (2) having an electrolyte layer (7) sandwiched between inside and outside electrodes (5, 6) to which a fuel gas is supplied, the fuel cell having an interior formed as an inside channel (3) for...

A hydrogen storage alloy comprises a hydrogen storage base 2 formed of a mixture of Mg and an alloy (Mg 2 Ni, for example), and a catalytic layer 3 covering a surface of the hydrogen storage base 2. The hydrogen storage alloy with this structure exhibits b...
