Influencia de la transferencia de masa sobre la potencia de una celda de combustión

Abstract

Mass transfer influence on fueL cell pouer. In the present work, the influence of Mass Transfer in the functioning of a Fuel Cell H2-O (HOK 6M) designed by our study group is studied With the aim of helping the ionic Mass Transfer and the maximum profit in the use of the electrocatalyst, it is proposed to dissolve the reactives (H2 and O2 ) in the alkaline electrolyte (HOK 6M) by means of individual bubling in countercurrent before the reactives arrive to the respective cell s compartment. The flow of the electrolite is modified in a wide range. Also the posibility of applying external ultrasonic vibrations is studied.The results of the experimental study show that the greatest obstacle was found in the ionic Mass Transfer of the reactives to the surface of the electrodes.
