Abstract: The invention provides an SOFC cooling system. For the feature that not all components work in the full operation process of an SOFC, a DC step-down transformer DCDC, a fan and a condenser are connected in parallel, and a solenoid valve is installed in each parallel pipeline for controlling on/off of each pipeline according to a corresponding signal. Compared with the traditional SOFC cooling system, the constant-flow serial cooling system will reduce pressure losses and the power of a water pump; a solenoid valve is installed in each parallel pipeline for controlling on/off of each branch according to a corresponding signal; considering the cooling requirements of SOFC during start-up, power generation and shutdown, all components are cooled in parallel through reasonable design of each parallel pipeline, consequently to improve the cooling effect and reduce the energy consumption; the invention also discloses a fuel cell and hybrid vehicle.

Abstract: An anti-biofouling shape-memory composite aerogel includes a unidirectional chitosan aerogel channel, a plant polyphenol coating, and a polyphenol/iron ion chelate. The plant polyphenol coating is evenly distributed on an inner wall of the unidirectional chitosan aerogel channel, and the polyphenol/iron ion chelate is located at a top end of the unidirectional chitosan aerogel channel. The anti-biofouling chitosan-based composite aerogel has an evaporation rate of 1.96 kg·m?2·h?1 at an illumination intensity of 1 kW/m2. The composite aerogel has shape-memory properties, and can quickly restore its original shape in water after extrusion, thereby accelerating the diffusion of substances to complete the modification of inner channels. In this way, desirable anti-biofouling ability is achieved, and excellent structural stability as well as continuous and efficient photothermal water evaporation are guaranteed in a complex water environment.

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.
