Abstract: A gas sensor system includes a membrane electrode assembly including a polymer electrolyte membrane and electrode layers disposed on opposing sides of the membrane, where an anode side of the sensor is defined at first side of the assembly and a cathode side of the sensor is defined at a second side of the assembly . The gas sensor is configured to detect a gas in an environment (e.g., a housing, a pipe, an open environment, etc.) by measuring an open circuit voltage between the anode and the cathode sides of the assembly. The gas sensor provides a rapid response that measures gas concentration in the environment and is further durable, reliable and relatively inexpensive to manufacture.
