Fig. 9 e (a) IeV curves of different kind hydrogen
(commercial high purity hydrogen, and hydrogen
generated from the hydrolysis of the 5vol. % CNTs/Al
composite). (b) The cell voltage profile measured at
constant current loads (10, 20 A) for PEMFC single cell when
hydrogen produced from the hydrolysis of CNTs/Al
composites was directly fed into the anode of PEMFC.
