Membrane Electrode Assemblies Based on Hydrocarbon Electrolytes with Nitrile Groups for Direct Methanol Fuel Cells

Measurement of Electrode Overpotentials for Direct Hydrocarbon Conversion Fuel Cells

Cathodic and anodic overpotentials were measured using current interruption and AC impedance spectroscopy for two separate solid oxide fuel cells (SOFCs). The fuel cells used yttria-stabilized zirconia (YSZ) as the electrolyte, strontium-doped lanthanum manganite (LSM) as the cathode, and a porous YSZ layer impregnated with copper and ceria as the anode. The Cu/CeO2/YSZ anode is active for the ...

A Quasi-Direct Methanol Fuel Cell System Based on Blend Polymer Membrane Electrolytes

Membrane Electrode Assembly (mea) Design for Power Density Enhancement of Direct Methanol Fuel Cells (dmfcs)

Liquid methanol concentration sensors for direct methanol fuel cells

Liquid-fed direct methanol fuel cells (DMFCs) are one of the most promising candidates for portable power electronics and automotive pplications due to their potentially high-energy density, simple storage, and distribution of the fuel. The concentration of methanol in the fuel irculation loop of a DMFC system is an important operating parameter, because it determines the electrical performance...

Silicon-based Proton Exchange Membrane for Micro Direct Methanol Fuel Cells

This paper presents our research on silicon-based proton exchange membranes for siliconbased micro fuel cell applications. The porous silicon membranes with a thickness of 20-40 m were fabricated. And the porous silicon-based proton exchange membranes were formed by using the combination of the porous silicon membranes and Nafion solution. The proton conductivities of the porous silicon-based P...
