Abstract
A new method of manufacturing a fuel cell, particularly for use in a breath alcohol detector, and the fuel cell created by the method. The fuel cell is constructed in two pieces, a mounting chip comprising a porous uncompressed substrate and an active element designed to fit within the mounting chip. Constructed in this way, electrolyte can flow from the mounting chip into the active element via near perfect capillary action to keep the electrode substrate full of electrolyte for long periods of time, increasing its useful life, especially under harsh conditions. Further, the capillary action need not work through a layer of electrode. Wire connections and arrangements are generally of no concern in this design as the reservoirs for electrolyte connect directly to the substrate and electrolyte does not need to pass through an electrode.
