A portable system for power generation based on hydrogen and a single proton exchange membrane fuel cell (PEMFC) has been built and operated. The fuel cell is fed in the anode with hydrogen stored in a metal hydrides cartridge, and in the cathode with oxygen from quiescent ambient air (‘air breathing’). The control electronics of the system performs DC–DC conversion from the low voltage (0.5–0.8V)...
In this work, the results obtained for Ni-La-Al catalysts developed in our laboratory for biogas reforming are presented. The catalyst 5% Ni/5% La 2 O 3 -γ-Al 2 O 3 has operated under kinetic control conditions for more than 40h at 700°C and feeding CH 4 /CO 2 ratio 1/1, similar to the composition presented in biogas streams, being observed a stable...
