Copolymers with chloro-polypropylene (CPP) and poly-ethylene-imine (PEI) were synthesized at different proportions 1:2, 2:3, 1:1, 3:2 in a solvent mixture of acetone and toluene at low temperature (35-50 °C) [1]. The membranes were produced by casting, to be used in alkaline ethanol fuel cells (AFCs) applications. Hydroxide resistance was measured by immersion in NaOH at different concentrations. The water uptake (WC) and the ethanol uptake (EC) were measured by immersion water retention test and immersion ethanol retention test. The measures of the membrane permeability to alcohol were taken using a diffusion cell and the material was proved in an hydrogen fuel cell of Bipolar Plate with Interdigitated Flow Fields. The platinum catalyst ink for the MEA was made with the suspension of co-polymer without casting [2].
