Connection system between hydrogen absorbing alloys and polymer electrode fuel cells

摘要

We have in view a system which converts the electric energy-generated from a solar battery-into hydrogen, and store it by hydrogen absorbing alloys. The polymer electrode fuel cells generates electricity using the hydrogen stored in the alloys when the solar battery doesn't work. In this paper, we experimented on a part of the system connecting the hydrogen absorbing alloys and fuel cells, designed an efficient utilization and confirmed the systems efficiency. As a result it is found that more than 80% of an amount of possible stored hydrogen is available and synthesis efficiency is over 24%.
