Abstract: A fuel cell system (10) and method of forming the fuel cell system including a base portion (14), formed of a singular body, and having a major surface (26). At least one fuel cell membrane electrode assembly (16) is formed on the major surface of the base portion. A fluid supply channel (32) including a mixing chamber (36) is defined in the base portion and communicating with the fuel cell membrane electrode assembly for supplying a fuel-bearing (34) to the membrane electrode assembly. A methanol concentration sensor (38) is positioned to communicate with the fuel cell membrane electrode assembly and the fuel- supply channel for regulating the mixture of fuel to the electrode assembly. An exhaust channel (38) including a water recovery and recirculation system (53) is defined in the base portion and communicating with the membrane electrode assembly.

Abstract: A calorimetric hydrocarbon gas sensor (10) includes an electrochemical oxygen pump (18), a sensing element (12), and a multi-layered substrate (26) separating the sensing element (12) from the electrochemical oxygen pump (18). The multi-layered substrate (26) includes a plurality of overlying insulating layers, in which at least one intermediate layer (60) supports a first primary heater (58), and in which another intermediate layer (52) supports a temperature compensation heater (50a, 50b). The primary heater (58) functions to maintain the calorimetric hydrocarbon gas sensor (10) at a constant, elevated temperature, while the active compensation heater (50a) functions to maintain substantially equal temperatures as determined by the thermometers (46a, 46b) located on an intermediate layer (48) overlying the compensation heaters (50a, 50b). Control circuitry is integrated with power measurement circuitry to measure differences in the heat produced by the compensation heater (50a) and the thermometer (46a) in an active region (100), and the heat produced by the compensation heater (50b) and the thermometer (46b) in a reference region (102).

Abstract: A multilayered ceramic integrated sensor (200) for monitoring auto exhaust gases is capable of existing in the relatively harsh environments of the exhaust stream of an internal combustion engine. The integrated sensor (200) may include discrete devices such as an oxygen sensor (104), a hydrogen sensor (206), an NOx sensor (208), and a carbon monoxide sensor (210). The device (200) may further include a temperature sensor (202) as well as a total combustion calorimetric sensor (101). The multilayered ceramic integrated sensor may be fabricated from a plurality of layers of ceramic material disposed in stacked relationship with respect to one another.
