A gas diffusion electrode and method of making the same. According to one embodiment, the electrode comprises a support layer, a first cushioning layer positioned on top of the support layer, a second cushioning layer positioned on top of the first cushioning layer, and a catalyst layer positioned on top of the second cushioning layer. The support layer is a mechanically stable, electrically-conductive, gas porous substrate, such as carbon fiber paper. The first cushioning layer, which is also gas porous, comprises a non-woven mat of electrically-conductive, chemically-inert fibers, preferably carbon nanofibers, bound together with a polymeric binder, such as polytetrafluoroethylene. The second cushioning layer is similar to the first cushioning layer, except that carbon black or a similar electrically-conductive, chemically-inert particulate material is included in addition to or instead of the fibrous material for the purpose of fine-tuning pore size.

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.

A method for the detection of carbon dioxide gas using an electrochemical sensor. The method includes exposing a gas to a sensor, which 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 method is highly sensitive and selective to carbon dioxide with a very rapid response time.

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.
