The impact of using a proton exchange membrane on alkaline fuel cell performance

Abstract

A hydrogen fuel cell was designed in the laboratory, operating in potentiostatic mode (1 V, 1.23 V, 1.5 V and 5 V), obtaining characteristic parameters that allow improving hydrogen production by means of electrolysis. For this, a proton exchange membrane, Nafi on 117, was adapted, which was subjected to an activation pretreatment, allowing us to compare its performance and function. Values for current density, degree of conversion, mass transfer coeffi cient and hydrogen fl ow generated in an instant (t) were obtained.
