A new, low-cost sensor that uses palladium and is for use in fuel cell systems has been developed.

Fuel cell component manufacturer Mikuni has announced the creation of the new sensor, which is able to detect the leakage of hydrogen in a concentration range of 0.01 to four per cent. This is below hydrogen explosion concentration range and Mikuni states that the product itself delivers high sensitivity and high durability.

The new sensor uses a ceramics-palladium composite at its centre and represents an important breakthrough for fuel cell development because it provides a cheap way to monitor hydrogen concentration in the systems.

This achievement was reached through the creation of a new technology that allows for the fine dispersal of palladium in ceramics.

Nikkei Business Publications reports that the new technology should come onto the market by the end of 2009 and Mikuni is also understood to be considering the sensor for use in applications other than fuel cells.
