Supported Ni—M materials for electrooxidation of hydrazine

摘要

A supported bi-metallic non-platinum catalyst that is capable of oxidizing hydrazine to produce, as by-products of energy production, nitrogen, water, and zero or near-zero levels of ammonia is described. The catalyst is suitable for use in fuel cells, particularly those that utilizes an anion-exchange membrane and a liquid fuel such as hydrazine.

主权项

1. A hydrazine fueled fuel cell comprising a catalyst comprising nickel, a second metal, and an electrically conductive supporting material, wherein the catalyst was formed by a mechanosynthesis-based method; wherein the catalyst selectively oxidizes hydrazine and produces ammonia at an amount of no more than 10 parts per million (ppm).
