“…An analytical model of an AEMFC can provide direct relationships between performance, design parameters, and operating conditions, as well as being time and computationally efficient. Several models have been created to simulate and understand water management during operation of an AEMFC . Those models were validated at low and moderate current densities, at which the carbonate process effect might be significant.…”

Over the past 10 years, there has been a surge of interest in anion-exchange membrane fuel cells (AEMFCs) as a potentially lower cost alternative to proton-exchange membrane fuel cells (PEMFCs). Recent work has shown that AEMFCs achieve nearly identical performance to that of state-of-the-art PEMFCs; however, much of that data has been collected while feeding CO -free air or pure oxygen to the cathode. Usually, removing CO from the oxidant is done to avoid the detrimental effect of CO on AEMFC performance, through carbonation, whereby CO reacts with the OH anions to form HCO and CO . In spite of the crucial importance of this topic for the future development and commercialization of AEMFCs, unfortunately there have been very few investigations devoted to this phenomenon and its effects. Much of the data available is widely spread out and there currently does not exist a resource that researchers in the field, or those looking to enter the field, can use as a reference text that explains the complex influence of CO and HCO /CO on all aspects of AEMFC performance. The purpose of this Review is to summarize the experimental and theoretical work reported to date on the effect of ambient CO on AEMFCs. This systematic Review aims to create a single comprehensive account of what is known regarding how CO behaves in AEMFCs, to date, as well as identify the most important areas for future work in this field.

“…Hence, good water management inside the membrane is required. Huo et al [29,266] made some assumptions to simplify the situation by developing a numerical, three-dimensional, multiphase model to investigate water transport at the anode of an alkaline PEM fuel cell. Li et al [211] also investigated water transport properties using an alkaline membrane.…”

“…An early one-dimensional, steady state study applied Tafel expressions to model electrode reactions and a multi-layer membrane model in order to study mass transport in an alkaline direct ethanol fuel cell [37]. Multidimensional, steady state and dynamic models were developed for the anode of H 2 /O 2 AEMFC to study the effect of operating conditions on the transient distribution of liquid water in the anode [38,39]. An analytical model was recently reported for an alkaline membrane direct methanol fuel cell to identify the most significant factors affecting cell performance including methanol crossover and water transport limitations [40].…”
