Obiettivo The proposed research programme of the Bulgarian institute is based on the effort of an English-Irish-German group coordinated by University of Bonn, to work on the development of a Direct Methanol Fuel Cell (DMFC) for an electric vehicle. The methanol anode and the oxygen cathode will be prepared using platinum metal catalyst on suitable substrates and a solid electrolyte consisting of a proton Exchange Membrane (PEM). Catalyst Characterization will be made via Electrochemical Mass Spectrometry and FTIR Spectroscopy. Special attention is given to operate the DMFC above 800 C via a gaseous feed of methanol. For this purpose three phase zone investigations on the basis of a Nafion 117 membrane will be carried out. the-objective is to design a DMFC with a power performance of P>50 mw/cm , with a low permitivity of methanol (<10 mA/cm2). Short term requirements are a cell voltage p400 mV at 100 mA/cm2 and 800 C. The detailed tasks allocated to the Bulgarian institute are the following: - Investigation and development of mixed precious metal catalysts out of pt, Ir and Ru on the bases of a Catalyst experience from Sofia using non-precious metals (Ni-B), - Test of smooth and roughened (small scale porosity),electrodes via the ring disc-ptential sweep technique in order to study the kinetics of methanol oxidation, the production of intermediates and poisoning Species, - Study of techniques of catalyst loading on appropriate supporting material (active carbon) in order to obtain catalytic electrodes with highly developed active surface area. The necessary 3-phase boundary will be created with hydrophobic binding materials developed in Sofia as the XC 30 (Hydrophobized carbon black) ensuring high diffusion flow of the gases to the 3-phase boundary sites and a good conductivity, - the semihydrophobic catalytic layers will be attached to proton conductive membranes (Nafion) and the performance of the methanol electrode will be tested.
