    摘要: An electrode suitable for use in a fuel cell includes a passive support having pores wherein the passive support has an asymmetric pore morphology with respect to at least one dimension of the passive support; and an electrode material positioned in the pores of the passive support. An exemplary electrode includes an electrode material of a metal and/or metal oxide. An exemplary porous electrode includes a deposited electrolyte layer that blocks at least some pores of the porous electrode. An exemplary method includes reducing an electrode material positioned in pores of a passive support to create secondary porosity and/or to limit agglomeration. Other exemplary devices and/or methods are also disclosed.

    摘要: A fuel cell or battery has an integral multifunction heater element operable as an integral heater, an integral temperature sensor, and/or an integral aid to current collection from the fuel cell. The integral multifunction heater element is embedded within the electrolyte, anode, or cathode, disposed in thermal contact with at least one of the electrolyte, anode, or cathode, and is formed of a thin film of material of suitable resistivity, such as a refractory metal or conductive oxide, patterned in a suitable pattern. Conductive terminals provide electrical contact to the thin film. The integral multifunction heater element may include a thermistor or thermocouple. Methods are disclosed for fabricating and using the fuel cell with an integral multifunction heater element.
