0000 A positive electrode active material which can improve cycle characteristics of a secondary battery is provided. Two kinds of regions are provided in a superficial portion of a positive electrode active material such as lithium cobaltate which has a layered rock-salt crystal structure. The inner region is a non-stoichiometric compound containing a transition metal such as titanium, and the outer region is a compound of representative elements such as magnesium oxide.

The present application discloses a fuel cell-based heat exchange device and a system. The solution comprises a primary heat exchange module, a burner, and a secondary heat exchange module. A hot-side input end of the primary heat exchange module is connected to an exhaust gas output end of a fuel cell stack, and a hot-side output end of the primary heat exchange module is connected to an input end of the burner. An output end of the burner is connected to a hot-side input end of the secondary heat exchange module, and a cold-side output end of the secondary heat exchange module is connected to an input end of the fuel cell stack. By providing the primary heat exchange module between the burner and the exhaust gas output end of the fuel cell stack, the temperature of stack exhaust gas entering the burner is reduced, thereby reducing the combustion temperature of the burner and the temperature of exhaust gas discharged from the burner, lowering the heat resistance requirements of the burner and the heat exchange module, and thus reducing implementation costs. The primary heat exchange module and the secondary heat exchange module are designed to reduce the number of exhaust gas distribution paths required for the burner output, thereby lowering design difficulty. Embodiments of the present application can be widely applied in the technical field of fuel cells.

Resumen de: US20260260909A1
A system and method are disclosed for establishing electronic connections between a circuit, such as a voltage monitoring circuit, and a fuel cell stack. Each cell in the fuel cell stack comprises an anode and a cathode, with provisions for connecting a voltage measurement device to monitor individual cell outputs. Due to the compact configuration of fuel cell stacks, direct access to these measurement points is often restricted, making traditional connectivity challenging. The connection system, based on a ribbon cable, addresses these constraints by offering a simplified and reliable means of connectivity that minimizes the risk of short-circuiting between closely spaced fuel cell terminals. Furthermore, the system provides enhanced resilience against disconnection due to external forces, such as shock and vibration, ensuring stable performance in environments like those encountered during rocket launches.
