New anodic diffusive layer for passive micro-direct methanol fuel cell

A novel multi-porous and hydrophilic anode diffusion layer for DMFC

“…Kyungmun Kang [4] thought if diffusion layer contained hydrophobic skeleton (PTFE), the methanol permeation would be restrained, so the cell's performance rose. A current density of 250 mA/cm 2 was obtained at 0.4 V. At the same time, Yuan [5] get the same result that hydrophobic skeleton was better for anode layer. The maximum power density of ca.…”

Effect of electrode variable contact angle on the performance and transport characteristics of passive direct methanol fuel cells

“…Liu and Wang [39] and Zago et al [40] compared several MEAs with different anode diffusion medium, and concluded that the water transport coefficient through the membrane with a hydrophobic anode MPL is several times smaller than those with a hydrophilic MPL or without anode MPL. Similarly, other experimental studies [41,42] also confirmed that anode MPL could reduce the methanol concentration in ACL, and thereby highly concentrated feed methanol might be used to increase the energy density. Kim et al [43] studied the effects of microstructure and powder compositions of anode MPL on the performance of a DMFC using a highly concentrated methanol solution.…”

Novel Options and Limitations of Methanol‐Based Production and Storage for Mobile Applications

“…The final metal loadings were 4.3 mg cm -2 and 1.8 mg cm -2 for the anode and cathode, respectively. These gas diffusion electrodes (GDE) were directly mounted together with Nafion® 117 membranes in the cell without hot pressing [10][11][12][13].…”
