Abstract

The invention discloses a circulating cooling water device for a fuel cell system, which includes a pure water circulation branch for three-stage heat transfer and utilization, a fresh water circulation branch and an external cooling water circulation branch; the pure water circulation branch utilizes pure water / fresh water The heat exchanger transfers heat to the fresh water circulation branch, and the fresh water circulation branch heats the hydrogen storage device and the oxygen storage device through the fresh water, and transfers the excess heat to the external cooling water circulation branch through the fresh water / external cooling water heat exchanger; 3 The multi-level circulating water can realize the layer-by-layer transfer of heat; the device has hierarchical heat exchange, convenient adjustment, and step-by-step utilization of heat, which can effectively improve the comprehensive energy efficiency of the system.

Description

technical field [0001] The invention belongs to the technical field of energy reuse, and in particular relates to a circulating cooling water device for a proton exchange membrane fuel cell system. Background technique [0002] The air-independent propulsion system refers to an energy system that can provide propulsion power and other power without relying on external air. Conventional air-independent propulsion systems mainly use the oxygen carried by themselves to provide combustion conditions for heat engines or electrochemical power generation devices, complete energy conversion, and provide propulsion power required for navigation. There are four main types of air-independent propulsion systems: fuel cells, heat engines, closed-cycle steam turbines, and closed-cycle diesel engines. [0003] At present, domestic and foreign technologies are relatively mature and have entered the practical stage mainly fuel cell systems and Stirling heat engine systems. In comparison, t...
