Abstract:
A miniaturized gas sensor including film type electrodes, and a solid ionomer electrolyte, for the detection of toxic gases, i. e. , carbon monoxide, and other oxidizable or reducible gases and vapors is described. The all-solid planar sensor cell has two or more film type electrodes arranged on a non-conductive planar surface of a supportive material. The electrodes are discrete and in intimate contact with the same solid polymer ionomer membrane. The sensor cell contains no liquid electrolyte and is operated in a potentiostatic or potentiodynamic mode. The unique feature of the sensor cell is that high sensitivity to a select gas or vapor is achieved by a novel three-phase contact area design for a sensing electrode which is easily accessible to the gas sample via small diffusion openings or holes that penetrate through the solid polymer ionomer membrane layer above the sensing electrode. A significant signal to background noise enhancement is achieved for these film type sensor cells by processes that increase the three-phase contact area.

Abstract:
A miniaturized gas sensor comprised of thick- or thin-film type electrodes, on a non-conductive supportive substrate, and in contact with a solid ionomer electrolyte, for the detection of toxic gases, i. e. , carbon monoxide, and other oxidizable or reducible gases and vapors is described. The all-solid planar sensor cell has two or more film type electrodes arranged on a non-conductive planar surface of a supportive substrate. The electrodes are discrete and in intimate contact with the same solid polymer ionomer membrane. The sensor cell contains no liquid electrolyte and is operated in a constant-voltage, potentiostatic or potentiodynamic mode. A high sensitivity to a select gas or vapor is achieved by a novel three-phase contact area design for a sensing electrode which provides contact with the solid ionomer electrolyte, as well as the gas sample via diffusion openings or holes that penetrate through the supportive substrate.

A high-voltage electrochemical-electrolytic capacitor. The capacitor includes a cathode comprising a plurality of electrically-conductive particles in intimate electrical contact with one another and disposed in a proton-conductive, electrically-non-conductive, solid ionomer matrix. The capacitor also includes an anode comprising a plurality of electrically-conductive particles in intimate electrical contact with one another and disposed in a proton-conductive, electrically-non-conductive solid ionomer matrix, the electrically-conductive particles of the anode differing in composition from the electrically-conductive particles of said cathode. The capacitor further includes a proton-conducting dielectric positioned between and in contact with each of the cathode and the anode, the proton-conducting dielectric comprising a solid ionomer. Preferably, the capacitor is assembled by constructing a first portion and a second portion, the first portion comprising the cathode and an extra thickness of solid ionomer on its inner surface, the second portion comprising the anode and an extra thickness of solid ionomer on its inner surface. When the first and second portions are brought together, the extended thicknesses of the solid ionomer jointly form the proton-conducting dielectric.

Abstract:
An electrochemical sensor is provided for the detection of carbon dioxide gas. The sensor includes a non-conductive solid substrate and at least one each of a metal oxide sensing electrode, a reference electrode and a counter electrode positioned on the substrate. A solid polymer electrolyte anion-exchange membrane is in intimate contact with the sensing electrode, reference electrode and counter electrode. The sensor is highly sensitive and selective to carbon dioxide and has very rapid response time.
