A sensor of liquid methanol for direct methanol fuel cells
Analytica Chimica Acta, 2021The methanol sensors are of significance to maintain the efficient and stable operation of direct methanol fuel cells (DMFCs). The issues, including stability, the relationship between temperature, current density and concentration need, however, urgent attention.

The construction of a simple direct methanol fuel cell (DMFC) for didactic purposes is described. Black platinum catalyst was electrolytically deposited on 0.3-mm-diameter nickel–chromium wire at −0.53 V vs RHE (corresponding to 8 mA/cm2 current) for 30 min from 0.02 M H2PtCl6–1 M HCl aqueous solution.

IEE Colloquium on Compact Power Sources, 1996
The principle fuel used to derive power from fuel cells has to date been hydrogen. Hydrogen is generated primarily by the reformation of hydrocarbon based feedstocks such as methane and methanol. Such generation immediately suggests a loss in efficiency in fuel utilisation as well as increased system cost. Thus the direct use of hydrocarbon based fuels

Methanol concentration estimation in a direct methanol fuel cell system
2014 American Control Conference, 2014An inferential sensor based on state estimation techniques is proposed for measuring the methanol concentration in an open-cathode direct methanol fuel cell. The strategies considered include full-state and reduced-state Luenberger observers along with a proportional-integral observer.

Systematic Experimental Analysis of a Direct Methanol Fuel Cell
Journal of Fuel Cell Science and Technology, 2006Different studies are carried out to compare the performances of different fuel cell constructive materials and operating conditions. In this work, a methodology for the characterization of DMFC experimental results in term of uncertainty and repeatability and for a systematic analysis of operating condition influence on performance is presented.
