DEVICE AND METHOD FOR THE HYDROLYTIC PRODUCTION OF HYDROGEN, DEVICE FOR PRODUCING ELECTRICAL ENERGY AND POSSIBILITIES FOR USAGE

摘要

The invention relates to compact and light-weight disposable storage devices for producing electrical energy having extremely high energy densities (>1 kWh/kg and >1 kWh/L), which are of immense interest in many fields of application. One possibility for realizing such energy storage devices is the use of metal hydrides in hydrogen generators, in which hydrogen is generated by hydrolytically splitting off a proton from water in conjunction with the metal hydride. In a second step, the chemical energy stored in the hydrogen can then be converted into electrical energy in a fuel cell. In the hydrolysis reaction, only half of the hydrogen produced originates from the metal hydride – the water used for hydrolysis supplies the other half.
