available space in a car. Actually, their design is compact even if some water is needed to dilute methanol. Portable applications and micro-fuel cells: The most important feature for a portable or micro fuel cell is a compact design. For a minimized size and weight, the cell has to work at ambient temperature. The low operating temperature of PEM fuel cell is a great advantage for portable applications. Actually, it is the only fuel cell able to work at ambient temperature [4]. For reasons similar to transportation application, it appears clearly that DMFC are more suitable than hydrogen fuel cells. Fuel cells are still a developing technology and need improvement in both technological performance and cost. 3. Direct Methanol Fuel Cell principle a. Generalities Basically, the direct methanol fuel cell is a proton exchange membrane fuel cell that is fed with an aqueous solution of methanol. The two catalytic electrodes where the methanol oxidation (anode) and the oxygen reduction (cathode) occur are separated by a membrane which conducts protons from anode to cathode, while other compounds diffusion is blocked. The combination of electrodes and membranes is called membrane electrode assembly (MEA). Each electrode is made of a gas diffusion layer and a catalytic layer (Figure 1). The state of the art in membranes is Nafion. It was created by addition of sulfonic acid groups into the bulk polymer matrix of Teflon. These sites have strong ionic properties and act as proton exchange sites. Aqueous methanol is fed at the anode side. It diffuses through the diffusion layer to the catalytic layer where it is electrochemically oxidized into mainly carbon dioxide protons and electrons. Protons formed during this reaction diffuse through the Nafion membrane to the cathode catalytic layer. They participate in oxygen reduction to form water at cathode side. Oxygen may be pure but can also come form air. - 16 -PDF Image | Direct Methanol Fuel Cell (DMFC) Performance
