Abstract: For safe operation of electronic devices, high-energy sources are needed. A promising solution is use of portable PEM fuel cells. It requires creation of systems for storage and generation of high-purity H2. Generation of large amounts of hydrogen over a prolonged time is best achieved in a hydrogen generator (HG) with a flow reactor where a concentrated solution of hydride (NaBH4, NH3BH3) passes through a fixed bed of granular catalyst. In this case, granulated Co-Ru catalyst is the most promising. HG with a batch reactor operating with solid pellets of mixture of NaBH4 and active cobalt catalyst is needed for a short-time generation of H2 which is important when charging batteries in the field. The active cobalt catalysts are formed from cobalt compounds directly in the in the reaction medium of boron-containing hydrides hydrolysis. Their structure was established using a set of modern physical methods, including EXAFS and neutron scattering.
