Abstract
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.
