HYDRAZINE SENSOR FOR QUANTITATIVE MEASURING HIGH HYDRAZINE CONCENTRATION FOR APPLICATION OF DIRECT HYDRAZINE FUEL CELL TO VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a flow-through electrochemical hydrazine sensor exhibiting a linear response at a high hydrazine concentration (2-4M) and applicable to a fuel cell vehicle while being suited for various applications.;SOLUTION: A hydrazine sensor includes an action electrode containing a hydrazine catalyst exhibiting a linear response at a hydrazine concentration of 2-4M. Specifically, the hydrazine catalyst comprises Ni as well as La, Zn, Mo or the other metal. Furthermore, the hydrazine catalyst comprises elements selected from among a group consisting of Ni0.95La0.05 and Ni0.85La0.15.;COPYRIGHT: (C)2016,JPO&INPIT
