Integration of metal hydride devices with polymer electrolyte fuel cells and electrolyzers for stationary applications

Abstract

This paper presents the experimental results of the system integration of a fuel cell (FC), an electrolyzer and a metal hydride hydrogen storage and purification system. A pilot scale experimental power installation H2Smart with an electric power of 1 kW is developed, and the results of its operation in different regimes are presented. The problems of hydrogen desorption for the supply of FC and hydrogen sorption from the electrolyzer at the start are shown. Possible solutions of this problem are proposed.
