TY - JOUR ID - citeulike:4340255 L3 - citeulike-article-id:4340255 N2 - An ammonia alkaline electrolytic cell for the production of hydrogen is presented. Challenges involved in using ammonia electro-oxidation for sustainable, low-cost, high-purity hydrogen production are identified and solutions are proposed. Electrodeposition was selected as a technique of preparing low-loading ammonia electrocatalysts. The efficiency of the electrolytic cell was improved by using bimetallic electrodeposited catalysts (at both electrodes) containing Pt and a low concentration of secondary metals (Ru, Ir). Pt–Ir deposits showed the highest activity toward ammonia oxidation. An experimental procedure is shown which minimizes the reversible deactivation of the electrode. Significant current densities were obtained (above 100 mA cm −2 ) during electrolysis testing at relatively low metal loading, low cell voltages, and high cell efficiencies. These results point to ammonia electrolysis as a promising candidate for an alternative process for low-cost, low-temperature, high-purity hydrogen production.
