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.
A wet standard calibration system which utilizes a heat conducting foam with the liquid therein to serve as a primary heating device to avoid the need to include mechanical agitation. The system is particularly useful for generating a vapor comprising water and ethanol which can be used for the calibration of breath alcohol testers.

Fuel cell gas sensors using an aperture in a fuel cell gas sensor that allows for determination of a gas proportion in a sample that includes more gas than could otherwise be safely sampled. The aperture is adjustable between an open and a closed state. The amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the amount of time that the aperture is in the open state. Alternatively, the amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the size of the aperture.

Method of compressing fuel cell electrodes, resultant fuel cell, and a housing for the fuel cell which utilizes electrolyte reservoirs
An electrode element and fuel cell and a new method of manufacturing a fuel cell, particularly for use in a breath alcohol detector. This new element includes a reservoir for extra electrolyte that can allow 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 and can be integrally formed with the electrode element to eliminate or reduce loss due to connective surfaces. 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.

An alcohol fuel cell sensor and the resultant alcohol breath tester assembly. The disclosed housing creates an alcohol breath tester assembly that protects the electrode sensor from liquid ingress, maximizes the sample contact with the platinum electrode surface, and provides a smooth path facilitating laminar flow of the sample through the sensor. This, in turn, provides good flushing of the volume without creating eddies or other turbulence. Additionally, the housing can utilize a vapor barrier layer in the assembly and restricts the layer from touching the electrode surface.
An improved alcohol fuel cell sensor and alcohol breath tester assembly where wires for connection to the electrodes are bent to have a generally planar base portion which may be positioned toward the center of the electrodes and an upright that then extends to the outside of the case. The uprights are generally perpendicular to the base allowing the wires to exit the housing toward the center, as opposed to toward an edge.

Calibration and accuracy check systems for a chemical sniffer, such as a breath alcohol tester, which utilize the dispensing of droplets with determinable concentration of alcohol and/or other liquids in a determinable number either directly to a reaction chamber, or into a carrier gas which can be sampled. The systems generally provide for accurate sample concentration being provided to the breath tester while also providing for a simplified system which can be easier to move, and require less operational complexity, than prior wet or dry calibrating systems.

SYSTEMS AND METHODS FOR DETERMINING THE POSITION OF AN ELECTRICAL SOLENOID
Provided herein are systems and methods which use the solenoid itself to sense the position of the armature within the solenoid, and therefore to determine the position of the solenoid's armature, and or any related devices whose movement is dependent on the armature's movement. Specifically, a system in which the change in self-induction that occurs when the armature moves relative to the solenoid coil is used to detect the location of the armature.
