A direct glucose anion exchange membrane fuel cell (AEMFC) with a near-neutral-state electrolyte was studied at varying temperatures of 20, 30 and 37 ° C at two different concentrations of glucose of 0.1 and 0.3 M and with three concentrations of electrolyte of 0.1, 0.2 and 0.3 M [PO4]tot. The prime objective was to show how specific energy (W kg-1 glucose) of the direct glucose AEMFC is related to the operation temperature and concentrations of the species. Current and voltage values were measured together with the pHs and conductivities of the electrolytes. No component analysis of the final products after the fuel cell operation were done as the oxidation products of glucose is believed to be mainly gluconic acid and unreacted glucose as shown in the low Coulombic efficiency based on the exchange of 24 e-. Temperature, electrolyte and glucose concentrations have shown to have pronounced effect for the achievement of the highest energy capacity of 5.15 Wh kg-1 glucose.
