Marine fuel cell power generation module and safe working method thereof

Abstract

The invention discloses a marine fuel cell power generation module which comprises a cabinet body, a box body, an air unit, a cooling water unit and a controller unit, the box body is composed of a box shell of a closed cavity structure, a fuel cell stack, a hydrogen unit and a purging pipeline, a gas outlet and a gas collecting port of the purging pipeline are evenly distributed in the box shell, purging gas is positive pressure inert gas, the box shell is sequentially provided with an explosion venting valve, a purge gas inlet and a purge gas outlet, the purge gas outlet is provided with a hydrogen concentration sensor and an audible and visual alarm, a gas interlocking valve is arranged at an inlet of the hydrogen unit, and the hydrogen concentration sensor, the audible and visual alarm, the gas interlocking valve and the controller unit are in communication connection. The invention also discloses a safe working method of the marine fuel cell power generation module, by monitoring and alarming the risk degree in the hydrogen leakage process in the box body, the explosion-proof and safety performance of the fuel cell power generation module is improved.

Description

technical field [0001] The invention belongs to the field of marine fuel cells, and in particular relates to a marine fuel cell power generation module and its safe working method. Background technique [0002] Compared with traditional marine power devices such as diesel engines, steam turbines, and gas turbines, fuel cell power systems are considered to be ideal power equipment for future green ships because of their advantages such as high energy density, low vibration and noise, and zero-emission environmental friendliness. They have broad market applications prospect. [0003] The fuel cell power generation module is the core equipment of the fuel cell power system, which is directly related to the efficiency, stability and safety of the marine engineering application of the fuel cell power system. Unlike the working environment of vehicles, fuel cell power generation modules for ships are usually installed in relatively airtight ship cabins, and ships operate far from...

AI Technical Summary

Problems solved by technology

However, the existing technology is aimed at the application of fuel cell vehicles, and its fuel cell power generation module is in an open environment, which is different from the marine fuel cell power generation module in a relatively closed ship cabin environment

In addition, the existing technology can be used for reference and used to improve the self-explosion-proof performance of the marine fuel cell power generation module to a certain extent, but there are still obvious shortcomings: compared with the hydrogen circulation pump and hydrogen supply pipeline, the hydrogen of the fuel cell stack The leakage rate is higher, so the existing technology integrates the fuel cell stack, air module, hydrogen module, cooling water module, and controller module into the same space box structure, which increases the hidden danger of hydrogen explosion to a certain extent
