Low-cost Hydrogen Sensor for Fuel Cell System

Mikuni Corp. has developed a low-cost hydrogen sensor for use in fuel cell systems that can detect leakage of hydrogen in the range of 0.01-4%, which is below the explosion concentration range. A ceramics-palladium (Pd) composite film is used in the heart of the sensor. The product boasts high sensitivity, high durability and low cost while maintaining excellent hydrogen selectivity.

Mikuni develops and sells products related to peripheral components of fuel cell systems such as various types of control and shutoff valves for use in water pumps of reformer in residential fuel cell systems. The latest sensor was developed as a part of the portfolio and was attained by establishing a technology to finely disperse Pd in ceramics. The company is planning to put it on the market by the end of 2009.
