Fuel Cell Concentration Sensors

ISSYS fuel cell sensing technology can be used with:

• Direct Methanol Fuel Cells (DMFC)
• Reformed Methanol Fuel Cells
• Ethanol-water Fuel Cells
• Ethylene Glycol-water Fuel Cells

DMFC's benefit when they employ a methanol concentration sensor. Fuel cell efficiency is improved when a constant methanol concentration can be maintained over time and temperature.

Applications for this technology include laptop computers, PDA's, digital cameras, remote battery chargers, video phones, fuel cell test & calibration equipment and video cameras.

ISSYS' new model FC6, offers unprecedented accuracy, a wide temperature range of performance (5 to 80ºC), a wide and variable concentration range (0 to 5%, 0 to 10%, 0 to 100% for example). The FC6 is also small enough (35mm x 28mm x 8mm) for embedded applications. See the FC6 Brochure for further detail.

The model 106C can be used for higher flow rates. See the Model 106 Brochure for further detail.

Using a fluid density measurement is an excellent way to measure the methanol to water concentration in a DMFC or methanol-based reformed fuel cell system. ISSYS' sensors can also work with ethanol, ethylene glycol and other fuel cell technologies.

Alternative Energy Applications:

The FC6 can also give a density output and be used with gasoline - ethanol, flex-fuels, distilled and refined ethanol quality, biodiesel sensing and blending and other alternative energy applications.
