2.2.6 Micro-Fuel Cell "Class"

Analytical Instruments 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.
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.
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.
Nominal output in air is 0.19 mA, and 90 % response time is 45 s.
Expected life in flue gas is 8 months.
