Alternative anodes for direct methanol fuel cells

Popis výsledku v původním jazyce

Proton exchange membrane type fuel cells (PEMFC) are potentially an efficient and ecologically friendly power source of the future. Especially a PEMFC based on the methanol oxidation reaction (MOR) is proposed as suitable for supplying portable devices [1]. The present drawbacks of the methanol PEMFC are the low degree of utilization of the catalyst and its poor resistivity to poisoning by carbon monoxide and other byproducts [2]. These two facts inflate the total price because the catalyst is usually based on platinum metals and their alloys.The design of the catalyst layer is of key importance. The layer must enable the fuel to reach the metal particles and be able to conduct the protons and electrons that have been generated, this means to exhibit ionic and electronic conductivity. The present design of the catalyst layer is usually based on a carbon-black supported catalyst impregnated with Nafion, but the problem of three-phase contact often arises (Fig. 1).The use of conducting p
