To avoid the hydrolysis reaction of sodium borohydride in producing hydrogen and to promote the direct electrochemistry reaction of borohydride to 8 electrons transfer are the key issues of DBFC. The by-product (hydrogen) of sodium borohydride can be measured in the half-cell measurements and single cell measurements were controlled by using the parameters taken in half-cell measurements. Carbon supported gold electrocatalysts were used in DBFC single cell measurements and the half-cell measurements indicate the gold electrode area promote anode electrochemical reactions. The rotating disk electrodes measurements may provide the flow rates parameters for DBFC single cell operations and the anode flow rate of 80ml/min was taken.
