- 9-3-3 Hydrogen generation by electrolysis of liquid ammonia as energy carrier
抄録
Ammonia (NH_3) is one of the most promising methods for storing and transporting hydrogen, because it has a high volumetric and high gravimetric hydrogen density. We have performed the direct electrolysis of liquid ammonia for hydrogen generation. To decrease electrolysis voltage, an electrode of Pt black electrodeposited on Pt plate to increase surface area is adapted for anode and cathode electrode of ammonia electrolysis. The electrolysis voltage at 1 mA/cm^2 decreases to 0.44 V from 1.0 V of Pt plate electrode. The hydrogen generation at 0.5 V is observed by gas chromatography after the electrolysis for 10 hours. To investigate the over potential properties, cyclicvoltammetry measurement by using a reference electrode of a Pt wire as a pseudo electrode was performed. The anode over potential is five times of the cathode one. Therefore, the anode reaction of nitrogen desorption is rate-determining step of over ammonia electrolysis.
