HEAT SENSITIZING CELL

PURPOSE:To perform the temperature sensing and electricity generation concurrently by filling specific first-order unsubstituted imidazole between a zinc negative electrode and a positive electrode diaphragm so that the melted object of this filler material acts as an electrolyte to generate the electromotive force between both electrodes. CONSTITUTION:A solid filler material using a mixture made of one or two types of first-order unsubstituted imidazole expressed by the formula as the essential component is sealed between a zinc negative electrode and a positive electrode diaphragm. In the formula, R indicates H, alkyl group, benzylic group, or toluic group, and R indicates hydrogen atom, methyl group, or benzylic group. The crystal powder, crystal fused solid, or the compressed compact of crystal powder of imidazole or the like reaches the melting point and is melted when the filler material is heated from the outside. Since the melted object is a liquid, it is leveled by the gravitational force, connects between both electrodes, acts as an electrolyte, and the electromotive force is generated. A heat sensitizing cell having the function to perform the temperature sensing and electricity generation concurrently can be obtained accordingly.
