Embedded Fuel-Cell Concentration Sensors


January 30, 2007 - ISSYS announced the launching of the world's first embedded density and chemical concentration sensor (Model FC6) based on the resonating tube technology. The model FC6 offers unprecedented measurement accuracy, stability, and speed at a very small size (1.4" x 1.1" x 0.3").


Dr. Nader Najafi, CEO of ISSYS, stated, "We developed the FC6 sensor in response to the urgent market need for a small embedded density and concentration sensor. In particular, the main driving application for this unique sensor was methanol concentration measurement for Direct Methanol Fuel Cell (DMFC) portable batteries. ISSYS is collaborating with Kyoto Electronics Manufacturing (KEM, Japan) to market this sensor to the DMFC market in Japan. ISSYS' methanol sensors will be displayed at the Fuel Cell Expo 2007, http://www.fcexpo.jp held February 7th-9th, 2007 in Tokyo, Japan. We are also looking for companies and investor groups wishing to apply this FC6 sensor to other markets".


Dr. Douglas Sparks, ISSYS Executive Vice President, stated, "Over the last 3 years, we spent a great deal of effort developing the FC6 which is much smaller than ISSYS' previous fluidic products. FC6 is the first of its kind and will open up many applications that were not possible in the past, including sugar mixtures for sodas, alcohol mixtures for beverages,
biodiesel blending, water in ethanol, ethylene glycol-water fuel cells, butanol for biofuel refinery, and any other application where accurate fluid
analysis is required."


DMFC and reformed fuel cell-powered laptop computers and remote battery chargers need methanol-water concentration sensors to operate efficiently and are poised for rapid growth. ISSYS' embedded sensors are made with microchips that can be produced at low-cost in high volume in order to make the emerging alternative energy products practical.
