REYES-PINEDA, Henry; LONDONO-RAMIREZ, Ramiro René  y  CARDONA-HERNANDEZ, Leidy Carolina. The impact of using a proton exchange membrane on alkaline fuel cell performance. Rev.fac.ing.univ. Antioquia [online]. 2015, n.77, pp.137-142. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.n77a16.

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, Nafion 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 coefficient and hydrogen flow generated in an instant (t) were obtained.

Palabras clave : Nafion 117; degree of conversion; production of hydrogen; mass transfer coefficient.
