Abstract

The performance of electrodes made from coconut-shell charcoal in alkaline fuel cells and metal/air batteries is reported. The electrode can be loaded with practically acceptable current densities of 500 - 2000 $A/m^2$ without deterioration for periods up to about 200 h. To achieve this performance, optimization of electrode structure was found to be necessary.Several chemical and physical techniques were employed to this end. Results show that coconut-shell charcoal is an excellent, low-cost substrate for porous carbon based air electrodes and further work may enhance its potentialities.
