VIASPACE Delivers Hydrogen Fuel Cell Humidity Sensor

VIASPACE, a company that transforms proven space and defense technologies from NASA and the Department of Defense into hardware and software solutions, announced today that it has begun shipments of its new VIASENSOR HS-1000 Humidity Sensor, designed to provide real-time measurement of the humidity level in hydrogen fuel cells. The initial deliveries of the VIASENSOR HS-1000 are to Fuel Cell Technologies, Inc., a leading supplier of fuel cell test systems based in Albuquerque, New Mexico.

The performance of hydrogen fuel cells using a Polymer Electrolyte Membrane (PEM) depends on the moisture level of the membrane. The membrane only conducts protons when it is hydrated or moist. The moisture is provided by water vapor in the incoming air or hydrogen stream. The VIASENSOR HS-1000 provides real-time measurements of the amount of water vapor in these gas streams. It is the only humidity sensor that provides in-situ, continuous and fast-responding dew point measurement. With its laser-based design, the VIASENSOR HS-1000 takes data measurements every five seconds, does not require specialized installation and is of no danger or harm to the fuel cell.

Dr. Carl Kukkonen, CEO of VIASPACE stated, "The VIASENSOR HS-1000 solves the key challenges of accurately measuring the fuel cell humidity levels in both high temperature and high humidity environments. It is designed to provide convenient and automatic data collection by computer via serial port or USB adapter. We believe this new product will help our customers optimize their hydrogen fuel cell designs. We recently demonstrated this new product at the Fuel Cell Expo in Tokyo, Japan with extremely favorable feedback."
