analyzed. The Micro-Fuel Cell is therefore a hybrid between a battery and a
true fuel cell. (All of the reactants are stored externally in a true fuel cell.)
2.2.2 Anatomy of a Micro-Fuel Cell
A Micro-Fuel Cell (MFC) is a cylinder only 1¼ inches in diameter and
1¼ inches thick. It is made of an extremely inert plastic, which can be placed
confidently in practically any environment or sample stream. The cell is
effectively sealed, although one end is permeable to oxygen in the sample
gas. The other end of the cell is a contact plate consisting of two concentric
foil rings. The rings mate with spring-loaded contacts in the sensor block
assembly and provide the electrical connection to the rest of the analyzer.
Figure 2-1 shows the external features of a typical cell.
