| 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.
