Electrolyte and water transfer through the porous electrodes of an immobilised-alkali hydrogen-oxygen fuel cell

Chitosan-based electrolyte composite membranesII. Mechanical properties and ionic conductivity

“…Compared to acidic PMFCs, an alkaline PMFC possesses several potential strong points, such as more effective oxidation of methanol [6], facilitated electrode kinetics [7], much lower level of methanol crossover [8,9], using inexpensive catalysts and the like [10][11][12][13]. Of many different kinds of anion-exchange membranes, ion-solvated polymer (ISP) composite membranes are especially attractive for alkaline PMFCs because they have much lower cost in comparison with the most other small fuel cell systems [14], and have the potential to show high power density and acceptable long-term stability [15]. Alkaline ISP composite membranes can be generally obtained by using suitable inorganic compound as ionic functionality, selecting some proper polymers as matrices and employing appropriate processing methods.…”
