The development of the technology for safe and efficient reversible solid-state hydrogen storage faces numerous technical problems, where the lack of understanding of heat and mass transfer peculiarities in micro and nano-structured materials during sorption/desorption processes with large volumetric thermal effects is one of the main. The integration of solid state hydrogen storage into the FC power supply systems results in appearance of new possibilities to increase the overall energy efficiency of the power supply systems together with identification of new technical challenges, such as the critical role of effective thermal conductivity in heat and mass transfer in storage tanks at sorption. The results of Russian R&D on the project “Reversible Solid State Hydrogen Storage for Fuel Cell Power Supply System” (HSSS) endorsed by International Partnership for Hydrogen Economy (IPHE) are presented in the following fields of activity:
1. Experimental investigations of heat and mass transfer in fine dispersed porous beds of hydrogen absorbing materials in porous tanks of various types with the aims of verification of mathematical model developed, optimization of heat exchanger design;
2. Experimental investigations of thermal processes at system integration of solid-state storage with PEM Fuel Cell with the aim of thermal management optimization.
