Simultaneous passive thermal management of PEM fuel cell and metal hydrogen storage system using heat pipes

摘要

The thermal coupling of PEM fuel cell (PEMFC) and Metal Hydride (MH) is expected to be promising, because as the PEMFC produces more power, more heat is generated accordingly [1], Thus the PEMFC is demanding for a higher rate of hydrogen and hence more heat is required by the MH to match its hydrogen discharge rate [2-4]. Heat pipes can thermally bridge MH and PEMFC, and due to their high thermal conductivities heat can be conducted passively; hence, parasitic energies associated with active methods of cooling can be avoided [5-7].
