Investigation of the kinetic properties of Co-La-Ce-B catalyst for sodium borohydride solutions to generate hydrogen for polymer electrolyte membrane fuel cell

We report the synthesis of Ce supported-Co-La-B (Co-La-Ce-B) catalyst and its catalytic activity.The synthesized Co-La-Ce-B catalyst for the first time is used to obtain the maximum hydrogen production rate from hydrolysis of sodium borohydride (NaBH 4 ).The synthesized Co-La-Ce-B catalyst indicates an effective performance in the hydrogen production from the hydrolysis of NaBH 4 .It is found that synthesized Co-La-Ce-B catalyst has a hydrogen production rate of 9,764.00mL/ min g and 19.63 kJ mol -1 .Moreover, hydrogen produced from NaBH 4 hydrolysis in the presence of a Co-La-Ce-B catalyst was used in polymer electrolyte membrane (PEM) fuel cell application.The open-circuit voltage of the single PEM fuel cell was measured at 0.87 V, which is higher than that of typical fuel cells.The efficiency value according to the power is 54%, while the efficiency value according to the ideal voltage is 71%.
