Abstract

Hydrogen generation system using aqueous $NaBH_4$ solution was developed for feeding small polymer electrolyte membrane fuel cells (PEMFCs). Ru was selected as a catalyst with its high activity for the hydrogen generation reaction. Hydrogen generation rate was measured with changing the solution temperature, amount of catalyst loading, $NaBH_4$ concentration, and NaOH (a base-stabilizer) concentration. A passive air-breathing 2 W PEMFC stack was operated on hydrogen generated using $20wt%\;NaBH_4+5wt%$ NaOH solution and Ru catalyst.
