Abstract
The authors considered two fabrication techniques in the fabrication of the membrane electrode
assembly. It was observed that catalytic deposition through electro-spraying was not successful for
chitosan and Nafion 117 membranes. Chitosan membranes are highly crystalline in their dry form and
as a result the sprayed Pt/C and PtRu/C catalytic layers became detached from the membrane surface
when immersed in a mixture of water and methanol. This was not the case when both membranes
were subjected to hot-pressing as both catalytic layers were successfully transferred onto the surfaces
of chitosan and Nafion 117 membranes. For chitosan membranes, the catalysts adhered onto the
membrane both in its dry form and when hydrated in distilled water
