Quantification of carbon dioxide poisoning in air breathing alkaline fuel cells

Effect of humidity on the interaction of CO2 with alkaline anion exchange membranes probed using the quartz crystal microbalance

“…Some studies have shown that the presence of carbonate ions can in fact improve fuel cell chemical stability and thus long-term operation [13,14]; whilst others have presented opposing results, through a reduction in both ionic conductivity and its impact on the hydrogen oxidation reaction (HOR) [16][17][18][19][20].…”

Methylated polybenzimidazole and its application as a blend component in covalently cross-linked anion-exchange membranes for DMFC

“…A primary advantage with the use of generic alkaline fuel cells (AFCs) is the possibility of using non precious (platinum-free) metal catalysts [5][6][7][8][9]. There are, of course, disadvantages with the use of AFCs, such as the formation of carbonate species (CO 3 2-and HCO 3 -) in the fuel cell, which risk the formation of precipitates in the electrodes [10][11][12][13]. It is difficult to compare the performance of AFCs containing AEMs (AEMFC) to the acidic analogue proton-exchange membrane fuel cells (PEMFC).…”

Development of Hydrogen Electrode for Alkaline Fuel Cell-1

“…K 2 CO 3 is insoluble in KOH electrolyte and gets deposited on the pores of electrode, thus, obstructing the functioning of the electrode. Nevertheless, many efforts are being made to overcome this problem [4]. Another problem is, developing a porous electrode that is chemically stable at higher concentration of KOH.…”
