We can supply a wide range of sizes and shapes of fuel cell wafers for incorporation into a sensor of a customer's design. The sizes and shapes available are listed below. Please note that the actual size of the wafers is slightly less than the stated value.

If a specific formulation and/or size is not listed below, please go to the quote request form and enter your requirements in the box provided.

Please note that the wafers below are for alcohol detection only.

Other sizes can be made available on request.

There are five options of electrolyte available.

  • Types 1, 2 and 3 may be suitable for interlocks, we would supply these for the customer to try out on their particular application to determine which is best.
  • Type 4 is for a "normal" temperature range, i.e. where the sensor might intermittently be exposed to a maximum of 50°C, and the results should be obtained through integration of the output signal.
  • Type 5 is suitable for low humidity environments, with the result being obtained again through integration.
  • Type 5 can be used up to 65°C if the result is obtained through peak measurement.
