Abstract

Abstract

In this study, the effect of Pd coatings made on Nickel foam on the efficiency was investigated by using SPEEK/PBI blend membranes in DBFC. Single cell tests have been carried out to see the effect of coatings' effectiveness under different conditions on fuel cell performance. As a result of the examination, the best performance in the fuel cell was obtained with a power density value of 120 mW / cm-2 applied with 4 V, 1 minute coating time. When looking at polarization and power curves of uncoated commercial Nickel foam and only Pd coated Nickel foam, it was seen that the performance of Pd coated Nickel foam was higher in the fuel cell with laboratory produced SPEEK/PBI blend membranes.
