Investigation of Fumasep(®) FAA3-50 Membranes in Alkaline Direct Methanol Fuel Cells

This paper describes the use of a commercial Fumasep(®) FAA3-50 membrane as an anion exchange membrane (AEM) in alkaline direct methanol fuel cells (ADMFCs). The membrane, supplied in bromide form, is first exchanged in chloride and successively in the hydroxide form. Anionic conductivity measuremen...

description This paper describes the use of a commercial Fumasep(®) FAA3-50 membrane as an anion exchange membrane (AEM) in alkaline direct methanol fuel cells (ADMFCs). The membrane, supplied in bromide form, is first exchanged in chloride and successively in the hydroxide form. Anionic conductivity measurements are carried out in both a KOH aqueous solution and in a KOH/methanol mixture. AEM-DMFC tests are performed by feeding 1 M methanol, with or without 1 M KOH as a supporting electrolyte. A maximum power density of 5.2 mW cm(−2) at 60 °C and 33.2 mW cm(−2) at 80 °C is reached in KOH-free feeding and in the alkaline mixture, respectively. These values are in good agreement with some results in the literature obtained with similar experimental conditions but with different anion exchange membranes (AEMs). Finally, methanol crossover is investigated and corresponds to a maximum value of 1.45 × 10(−8) mol s(−1) cm(−2) at 50 °C in a 1 M KOH methanol solution, thus indicating that the Fumasep(®) FAA3-50 membrane in OH form is a good candidate for ADMFC application.
