Abstract

The design and performance of an alkaline ammonia electrolyzer for hydrogen production and its feasibility for fuel cell applications are presented in this work. By comparison of the energy consumption and power for the ammonia electrolytic and water electrolyzers at different hydrogen production rates, the total energy consumption by the water electrolyzer as well as the power required is much higher than for the ammonia electrolytic cell (up to 65% higher). For this reason, the ammonia electrolytic cell has the potential to operate by stealing part of the energy of a PEM hydrogen fuel cell. Furthermore, the lower energy consumption when compared to a water electrolyzer indicates that the ammonia electrolytic cell can be operated by renewable energy sources to produce hydrogen on demand. In this paper, we suggest an electrochemical study on a Pt-based ammonia oxidation and hydrogen evolution electrocatalysts. These materials are very interesting; particularly, Pt-Ir supported on carbon improves the performance of Platinum on Carbon, reference commercial, so that the energy consumed by the ammonia electrolytic cell is lower.
