In order to optimise the performance of Proton Exchange Membrane Fuel Cells (PEMFCs) and maximise their life cycle, water content has be properly controlled. This paper presents a model-based method determine effect load on PEMFC in PEMFCs using Acoustic Emission (AE) measurements. The developed model was implemented COMSOL verified single proton exchange membrane fuel cell (FC) operated under ...

Water loss and the coincident increase in membrane resistance to proton conduction are significant barriers to high performance operation of traditional proton exchange membrane fuel cells at elevated temperatures where the relative humidity may be reduced. We report here approaches to the development of high temperature membranes for proton exchange membrane fuel cells; composite perfluorinate...

In this work membrane (proton exchange membrane) by using the blend polymers (polyethersulfone (PES), Expandable polystyrene (EPS), polyvenylidinefluride polymer (PVDF)) were prepared. This was modified adding organic sulfonic acid to solution precasting process, and sulfonated dipping it in diluted sulfuric (H2SO460%) post casting process. The sulfonation confirmed via FTIR spectra. characteri...
