Cell-Based Experimental Analysis of a Proton Exchange Membrane Fuel Cell (PEMFC)

Abstract

This study is focused on cell-based experimental analysis of Proton Exchange Membrane Fuel Cell (PEMFC) with sodium borohydride (NaBH4). The change in cell-based voltage values of 10-cell PEM fuel cell at two different temperatures was evaluated by keeping at constant load NaBH4, pure water and citric acid (C6H8O7) which is used as a catalyzer. 3 g NaBH4, H2O/NaBH4: 2 mol/mol (x=0), and C6H8O7 catalyzer/NaBH4: 0.1 g/g and 250 cm3 of reactor volume production were realized. When the water temperature was raised to 60 ºC from 40 ºC, total voltage value increased by 6.1%. While, in the experiment of 40 ºC, the interchange in voltage values were between 0.53 V and 0.78 V, the mean values in the experiment of 60 ºC were between 0.61 V and 0.79 V.
