PRELIMINARY STUDY OF THE INTEGRATION OF A COMMERCIAL METAL HYDRIDE UNIT FOR HYDROGEN STORAGE AND A COMMERCIAL PEM STACK

pages 201-208
Sinopsis
In this paper the integration of a commercial metal hydride
storage unit with a commercial PEM (Proton Exchange
Membrane) stack has been analyzed. A reversible metal
hydride requires heat power to release the stored H2 and a PEM stack using a H2 flow produces also heat power. The performances of the storage unit at three different temperatures were tested and the energy request to release the H2 was
calculated. At the same time, a commercial PEM stack of
800 W has been tested to analyze the produced electric and
thermal power at different current density and operating
conditions. Finally, the possibility to feed the PEM stack with the H2 released by the metal hydride unit, using the heat produced by the same stack, was analyzed and discussed.
