Operational Theory 3000TA- EU 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
