2.2.6 Micro-Fuel Cell “Class”

TBE manufactures Micro-Fuel Cells with a variety of characteristics to give the best possible performance for any given sample conditions. A few typical Micro-Fuel Cells are listed below with their typical use and electrical specifications.

2.2.6.1 Class A-3 Cell

The class A-3 cell is for use in applications where it is exposed continu- ously to carbon dioxide concentrations between 1 % and 100 % in the sample gas.

Nominal output in air is 0.20 mA, and 90 % response time is 45 s. Expected life in flue gas is 8 months.

2.2.6.2 Class A-5 Cell

The class A-5 cell is for use in applications where it is exposed intermit- tently to carbon dioxide concentrations up to 100 % in the sample gas.
