Improvement of the performance of metal hydride pump by using phase change heat exchanger

摘要

Some metals and alloys called metal hydrides (MHs) may react reversibly with a large amount of hydrogen under certain conditions. Such materials may be used not only as hydrogen storage carriers but also as energy conversion materials. Thermally driven metal hydride pump (MHP) system is a promising candidate to utilize low-grade heat because it has no mechanical moving parts and uses an environmentally friendly working fluid.
