Modelling and Control of an Onboard Fuel Processor for Indirect Methanol Fuel Cell Vehicles

In this paper, the dynamic model of a fuel processor for hydrogen production from steam reformation is first introduced. The fuel processor is built according to an integrated burner and reformer bi-catalyst plate configuration. The model is then coupled with the one of a PEM fuel cell, and the overall simulator is used to analyze different control configurations. It is shown that the limited d...

Optimal Concentration Control for Direct Methanol Fuel Cells

Two modifications to a reference direct methanol fuel-cell (DMFC) system are considered to improve methanol fuel utilisation. Fuel utilisation can be optimised by minimising the parasitic methanol crossover by manipulating methanol concentration in the fuel cells. Simulations of the two systems indicate that there is considerable potential to increase fuel utilisation for dynamic concentration ...

Towards neat methanol operation of direct methanol fuel cells: a novel self-assembled proton exchange membrane.

We report here a novel proton exchange membrane with remarkably high methanol-permeation resistivity and excellent proton conductivity enabled by carefully designed self-assembled ionic conductive channels. A direct methanol fuel cell utilizing the membrane performs well with a 20 M methanol solution, very close to the concentration of neat methanol.
