Shanghai Zhuowei Hydrogen Multi-Stack Fuel Cell Cooling System Utility Model Patent CN 218471995 U

This document is the granted Chinese utility model patent CN 218471995 U, titled 多堆燃料电池冷却系统 (multi-stack fuel cell cooling system), owned by Shanghai Zhuowei Hydrogen Technology Co., Ltd. (上海卓微氢科技有限公司). The patent was filed on 2022-07-22 and announced on 2023-02-10, and contains one page of claims, five pages of description and two pages of drawings.

The claimed system consists of a cooling water tank and a pump whose outlet feeds three cooling branches connected back to the tank through a return pipe. The branches include switch valves, fuel cell stacks, three-way solenoid valves, intercoolers, check valves, a PTC heater, a thermostat and temperature sensors, all electrically connected to a fuel cell controller. By routing coolant so that waste heat from the upstream stacks preheats the downstream stacks, the rear stacks can be started quickly without consuming extra electric energy, which the patent states improves the energy utilization of the system. This manual is written in Chinese.
