摘要： Flexible fuel cell sensors and methods of making and using the same are provided. A fuel cell sensor can be used for the detection of, for example, isopropyl alcohol (IPA), and the working mechanism of the fuel cell sensor can rely on redox reactions. The fuel cell sensor can include a proton exchange membrane (PEM), an anode disposed on a first surface of the PEM, a cathode disposed on a second surface of the PEM opposite from the first surface, and a reference electrode disposed on the first surface of the PEM and spaced apart from the anode.

摘要： A reference electrode which is stable over a wide range of temperatures, pressures and chemical conditions is provided. The subject reference electrode according to the present invention comprises a tubular enclosure composed of quartz having a distal, closed end and a proximal, open end. An insulating ceramic rod is seemingly connected to the opening in the closed distal end of the enclosure to form micro-cracks between the ceramic rod and the quartz enclosure (called a cracked junction, CJ). The CJ gives a very tortuous path for ion conduction from inside the reference electrode (RE) to a working electrode (WE). Inside the tubular enclosure is an electrical lead (e.g., a silver wire) disposed in an electrolyte comprising a mixture of alkaline metal salts (e.g., AgCl and KCl), extending from the electrolyte upward through a sealing means at the proximal end of the quartz enclosure.

摘要： An electrochemical oxygen sensor is provided. The electrochemical sensor includes a housing having first and second compartments, a sensing electrode disposed within the first compartment of the housing, a consumable anode disposed within the second compartment of the housing, a porous separator between the sensing electrode and consumable electrode that separates the first and second compartments and an electrolyte saturating the porous separator and consumable anode. A first aperture on a first end of the housing extends between an outside surface of the housing and first compartment that allows gas access to the sensing electrode. A venting system on a second, opposing end of the housing includes a second aperture extending between the outside surface of the housing and second compartment and has a predetermined permeability that controls pressure in the second compartment and loss of moisture from the sensor.

摘要： A flowing junction reference electrode comprising a liquid junction member matched with a filter. The junction member and the filter are situated between a reference electrolyte solution and a sample solution. An array of nanochannels spans the junction member and provides fluid communication between the electrolyte solution and the sample solution. The filter is configured to allow a greater flux of electrolyte than that associated with the junction member. Preferably, the number of pores is greater than the number of nanochannels. The filter is preferably configured to have pores with an inner diameter that is the same or less than the inner diameter of the nanochannels. In some embodiment, the resistance of the filter is made lower relative to the resistance of the junction member by selecting suitable length, number, and inner diameter size for the pores of the filter relative to the nanochannels of the junction member.
