Web1 jul. 2003 · A fuel cell was developed using borohydride solutions as the fuel. The cell consisted of an anode made of a Zr-Ni alloy, a cathode made of Pt/C, and a Na + form Nafion membrane as the electrolyte. The borohydride-fueled cell showed an open-circuit voltage of 1.3 V, compared with 1.0 V for a hydrogen gas-fueled one. The anode … Web12 mei 2003 · The fuel was 300 mL alkaline borohydride solution containing 10 wt % and 20 wt % NaOH. It was pumped into the cell at a flow rate of about 0.2 L/min. The cell temperature was controlled through regulating the fuel temperature to 50, 70, or for …
