Descripción
The preparation and characterization of a monolithic mesoporous carbon structure, which could be used as diffusion layer in PEM and DMPEM micro fuel cells, is described. Several characteristics of the monolithic carbon were studied, such as specific surface area, pore size distribution, bulk electrical resistivity, contact resistance with graphite plates, along with the wettability, imbibition and permeability of methanol aqueous solution. These properties were compared to those reported for commercial carbon paper and carbon cloth materials commonly used as diffusion layers in PEM fuel cells. The electrical properties of the mesoporous carbon meet the requirements to be employed as diffusion layers in PEM stacks assembled at pressures above 15 bar. The rapid spreading and imbibition of concentrated methanol solutions in the mesoporous carbon, as well as the permeability of the aqueous methanol through it, also make this mesostructured carbon a possible candidate for diffusion layer and catalyst support in passive direct methanol micro fuel cells.
