英文摘要Two kinds of CoX2 (X = Cl-, NO3-) are adopted as the accelerators for the hydrolysis reaction of NaBH4, which is a promising H-2-supply method for proton exchange membrane fuel cell (PEMFC). In the reactor, the initial H-2 generation is caused by the reaction between pre-infused CoX2 solution and subsequently imported NaBH4 solution, and some precipitates are in situ formed on the catalyst bed by this way; and the following H-2 generation is promoted by these precipitates. It is found that there are competitive reactions during H-2 generation from an NaBH4 to NaOH solution, the anions of CoX2 are crucial to the reaction pathways, which led to the formation of highly active Co-B or inactive Co(OH)(2). The effects of the CoX2 concentration, the NaOH concentration, the NaBH4 feeding rate and the NaBH4 concentration on H-2 generation performances are discussed and compared. (C) 2009 Professor T.
