regenerative fuel cell
Regenerative fuel cells produce electricity from hydrogen and oxygen and generate heat and water as byproducts, just as other fuel cells do. However, regenerative fuel cell systems can also use electricity from solar power or some other source to divide the excess water into oxygen and hydrogen fuel, a process known as electrolysis. This is a comparatively young fuel cell technology being developed by NASA and others.
