Characterisation of direct methanol fuel cells under near-ambient conditions (2006)
Direct methanol fuel cells have been characterised under ambient conditions. By operating the cathode with hydrogen as well as air, the half-cell and full-cell overvoltages have been found. Both the...
Characterisation of a portable DMFC stack and a methanol-feeding concept (2006)
A portable direct methanol fuel cell stack is characterised, together with a novel methanol-feeding concept. The amounts of water and carbon dioxide in the cathode and anode outlets respectively are...
WO2005039748 A UPAB: 20050613 NOVELTY - Device for increasing the fuel concentration in a liquid mixture of fuel and carrier comprises a fuel storage unit with a flow passage comprising a membrane...
Tüber, K., Oedegaard, A., Hermann, M., Hebling, C.
The flow-field design can have great influence on the operating performance of both proton exchange membrane fuel cells (PEMFCs) and direct methanol fuel cells (DMFCs). Inhomogeneous transport of...
Influence of diffusion layer properties on low temperature DMFC (2004)
Oedegaard, A., Hebling, C., Schmitz, A., Moller-Holst, S., Tunold, R.
The effect of the diffusion layer on the performance and mass transport in a direct methanol fuel cell at ambient conditions is reported. Carbon cloths with variable Teflon contents and pore sizes,...
Portable size DMFC-stack (2004)
Oedegaard, A., Hufschmidt, S., Wilmshoefer, R., Hebling, C.
A small, low temperature, direct methanol fuel cell stack for portable applications has been developed. Several flow field designs were investigated with respect to stable operation and high...
