Electrode formulations with different materials and manufacturing techniques were tested electrochemically in order to assess their stability and activity in long-term operations. Cathode electrocatalysts, such as CoTPP, Ca0.9La0.1MnO3 and Pt-Co alloys were incorporated in high surface area carbons and operated at a constant load of 100 mA cm2, 80 Â°C and an electrolyte concentration of 6 M KOH. Similarly, anode catalysts with Pt-Pd bimetallic combinations were also tested and ascertained in half-cell measurements. Surface area measurements and Transmission Electron Microscopy (TEM) analyses were carried out both before and after the electrochemical test procedures. The electrodes were incorporated into a seven and two cell module design of the external and internal manifolding types and the experiences gained from these design principles are described, respectively. Furthermore, a biomass fed AFC module with all the system descriptions, steps, and a demonstration layout of producer gas to alkaline fuel cell are examined and discussed. Wood charcoal and agro-residues were used as feedstock and as a primary fuel. Power output of the different feedstock in a producer gas fed alkaline fuel cell has the shown potentiality and efficiency to be applied as a stand alone power generator.
