 Abstract
Sodium borohydride, , shows a number of advantages as hydrogen source for portable proton exchange membrane fuel cells(PEMFCs). Properties of hydrolysis reaction using unsupported Co-B, Co-P-B catalyst were studied. BET surface area of catalyst, yield of hydrogen, effect of concentration and durability of catalyst were measured. The BET surface area of unsupported Co-B catalyst was and this value was 18 times higher than that of FeCrAlloy supported Co-B catalyst. The hydrogen yield of hydrolysis reaction by unsupported catalysts using 20~25 wt% solution was 97.6~98.5% in batch reactor. The hydrogen yield decrease to 95.3~97.0% as the concentration of solution increase to 30 wt%. The loss of unsupported catalyst was less than that of FeCrAlloy supported catalyst during hydrolysis reaction and the loss increased with increasing of concentration. In continuous reactor, hydrogen yield of hydrolysis was 90% using 1.2 g of unsupported Co-P-B catalyst with hydrogen generation rate.
