Graphene-carbon nanotubes (G-CNTs) composite material was prepared as the anodic micro porous layer (MPL) carbon material to fabricate the anodic diffusion layer for a passive direct methanol fuel cell (DMFC). The crack-free anodic MPL was obtained with the G-CNTs, leading to significant improvement in the cell's performance. The maximum power density of∼41.6mWcm−2 at a temperature of ∼25 °C was achieved...
The addition of carbon nanotubes (CNTs) into anodic micro-porous layer (MPL) of the membrane electrode assembly significantly improves the performance of the passive micro-direct methanol fuel cells (DMFCs). The maximum power density of ca. 32.2mWcm −2 at a temperature of ca. 25°C and under air-breathing mode is achieved with pure CNTs as anode MPL material. Impedance analysis and cyclic voltammetric...
