2.2.6 Micro-Fuel Cell “Class”
TAI 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 electri-
cal specifications.
2.2.6.1 Class A-3 Cell
The class A-3 cell is for use in applications where it is exposed con-
tinuously 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 inter-
mittently to carbon dioxide concentrations up to 100 % in the sample gas.
Nominal output in air is 0.19 mA, and 90 % response time is 45 s.
Expected life in flue gas is 8 months.
