This article presents the first systematic study of the effect of Relative Humidity (RH) on the water content and hydroxide ion conductivity of quaternary ammonium-based Alkaline Anion-Exchange Membranes (AAEMs). These AAEMs have been developed specifically for application in alkaline membrane fuel cells, where conductivities of >0.01 S cm(-1) are mandatory. When fully hydrated, an ETFE-based r...

This paper reports on the performance of an alkaline-acid direct chloro ethanol fuel cell (AA-DCLEFC) that is composed of an alkaline anode, a membrane and an acid cathode. The effects of membrane thickness and the concentration of various species at both the anode and cathode on the cell performances are investigated. It has been demonstrated that the peak power density of this AA-DCLEFC that ...

Fuel cells (FC) have been developed for automobiles and stationary power units. In addition to a generator function, we propose new application of hydrogen isotope separation. this paper, deuterium (D) separation is investigated by two types AFCs with platinum (Pt) or ruthenium (Ru) anode catalysts. The characteristics the are evaluated pure protium (H) gas separately. case Pt catalyst, cell cu...
