    摘要： Motorized vehicles are provided which may a device configured to convert a fuel comprising a hydrocarbon, an alcohol, or both, to an exhaust comprising CO2; and a tank configured to store, under pressure, the exhaust comprising CO2 and an inlet port configured to receive the exhaust from the device. The device may be a solid oxide fuel cell (SOFC). The tank may be a co-storage tank configured to store, under pressure, the fuel comprising the hydrocarbon, the alcohol, or both, and the exhaust comprising CO2, the co-storage tank further comprising an outlet port configured to deliver the fuel to the device. Methods of using the motorized vehicle are also provided.

    摘要： Oxygen electrodes are provided, comprising a perovskite compound having Formula (I), Sr(Ti1-xFex-yCoy)O3-δwherein 0.90≥x≥0.40 and 0.02≥y≥0.30. Electrochemical devices comprising such oxygen electrodes are also provided, comprising a counter electrode in electrical communication with the oxygen electrode, and a solid oxide electrolyte between the oxygen electrode and the counter electrode. Methods of using such electrochemical devices are also provided, comprising exposing the oxygen electrode to a fluid comprising O2 under conditions to induce the reaction O2+4e−→2O2−, or to a fluid comprising O2− under conditions to induce the reaction 2O2−→O2+4e−.
