The electrochemical oxidation of various polyhydric alcohols, ethylene glycol, glycerol, meso ‐erythoritol, and xylitol, on a platinum electrode was investigated systemematically in acidic H 2 SO 4 , and in alkaline KOH and K 2 CO 3 solutions to evaluate the potential of these polyhydric alcohols as fuels in micro‐fuel cells for portable electronic devices. All polyhydric alcohols tested in the present study showed high reactivities in both alkaline solutions. Ethylene glycol showed the highest reactivity. Although the reactivity of ethylene glycol was lower in K 2 CO 3 than in KOH, the carbonate solution is a potential candidate as an electrolyte solution due to its resistance to solution carbonation. Furthermore, ethylene glycol showed much less significant electrode poisoning by adsorbed CO upon oxidation in alkaline solution.
