Abstract: A preparation method for improving light efficiency and stability of light storing ceramics is provided. Calcium ethanol solution is added into titanium precursor solution firstly and oleic acid dispersant is added, pure water and the light storing powder are subsequently added to obtain a light-storing powder-calcium titanate gel, and dried, crushed and sieved to obtain xerogel powder. Glass matrix material, sieved xerogel powder and another dispersant are placed into a granulator, and directly mechanically stirred and granulated after adding pure water. A plasticizer is added after stirring 4˜8 h, and continuously stirred for 1˜3 h to obtain a mixture, pressing, drying and firing. Calcium titanate is manually introduced to protect the light-storing powder from hydrolysis or high-temperature oxidation. It can also change the propagation path of fluorescence inside ceramics, improve light absorption and fluorescence output efficiency and is conducive to ceramic molding.

Abstract: The present application discloses a car power supply system and a solid oxide fuel cell vehicle. The car power supply system specifically comprises a first battery, a vehicle control unit (VCU), a lithium battery management system, a solid oxide fuel cell control unit, a second battery, a first relay and a second relay. If a solid oxide fuel cell controlled by the solid oxide fuel cell control unit provided by the present application cannot stop working within a short time, the first relay restores the first battery to power the VCU and the lithium battery management system after a start switch stops power supply by the first battery, so that the solid oxide fuel cell control unit is powered by the second battery to make the cell work normally and realize power off, thereby preventing the problem that the solid oxide fuel cell cannot work due to rapid power failure of the vehicle.
