Abstract
This paper reviewed the technological development of alkaline fuel cell (AFC). Although the technology was popular in 1970s and 1980s, there has been a decline in AFC research over the past decade, mainly due to the poisoning of CO2. Continuous efforts have demonstrated that CO2 concentration could be reduced to an acceptable level by a number of viable methods such as absorption, adsorption, electrochemical process, electrolyte circulation, use of liquid hydrogen, and use of solid anionic exchange membranes. Literature survey showed that AFC lifetime could achieve up to 5000 hours. In addition, the use of ammonia as a fuel for AFC was identified as a promising technology. Comparison between AFC and proton exchange membrane fuel cell (PEMFC) was presented to evaluate the AFC technology and its economics. The present review and assessment showed the promise of AFC for the coming hydrogen economy and sustainable development.
