This paper deals with the kind of the bioorganic fuel cells that are equipped with or without ion exchange membranes The bioorganic materials of interest are alcohols (methanol ethanol) and glucose which are obtained from renewable energy sources such as biomass The operation temperatures of the direct fuel cells cover from room temperature up to 150 C The direct bioorganic fuel cells belong to the subject area of Advanced fuel cells of the Working group 4 in the EU COST Action 543 among the collaborating Universities and Institutes Bioorganic fuel cells are suitable for application in small portable power sources such as backups battery chargers and in electronic devices A number of current and earlier works are summansed and advances are highlighted in this area with special emphasis on glucose as a fuel (C) 2010 Professor T Nejat Veziroglu Published by Elsevier Ltd All rights reserved
