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
The Micro-Fuel Cell is a cylinder only 11/4 inches in diameter and
11/4 inches thick. It is made of an extremely inert plastic, which can be
placed confidently in practically any environment or sample stream. It 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 illustrates the external features.

Refer to Figure 2-2, Cross Section of a Micro-Fuel Cell , which
illustrates the following internal description.
