ISSYS & KEM to Present Methanol Concentration Sensor Posters at Two Upcoming Fuel Cell Conferences

YPSILANTI, Mich.--Oct. 1, 20054, 2005--Integrated Sensing Systems, Inc. (ISSYS) in Ypsilanti, Michigan, announced today that it will have poster presentations at the upcoming Fuel Cell Summit 2005, http://www.fuelcellsummit.com held on October 24th in Unicasville, CT and at the Fuel Cell Durability Conference, http://www.knowledgefoundation.com/ held on December 8-9, 2005 in Washington DC.

The posters will cover the small methanol concentration sensors under development, targeting the active Direct Methanol Fuel Cell (DMFC) market. ISSYS is working with Japanese based, Kyoto Electronics Manufacturing Company (KEM) on this project http://www.kyoto-kem.com/top.html. These small sensors can also be utilized in a variety of other industrial and analytical applications for the need of a low-cost, accurate, small, inline density or chemical concentration sensors.

ISSYS' sensors are based on Micro ElectroMechanical System (MEMS) technology. This microfluidic technology offers advantages in system and sample size, cost and reliability over current approaches to fluidic density, methanol concentration and chemical concentration measurement, http://www.mems-issys.com/html/density.html.

The use of a methanol concentration sensor is essential for the practical application of a variety of DMFC technologies. Currently ISSYS' technology offers the only efficient solution for the DMFC application, particularly due to its outstanding accuracy, stability and potential low cost. Furthermore, unlike previous methanol concentration sensors, ISSYS' products operate over a wide temperature range and are not sensitive to chemical impurities.

Fuel cells offer a big improvement in portability over conventional battery packs. Applications for DFMC technology include laptop computers, PDAs, camcorders and other portable consumer electronics.
