Fuel cell module with water and thermal management capability

Abstract

A fuel cell module with water and thermal management function comprises a fuel cell stack, a distribution unit, a power management unit, a voltage reducing and heating submodule, a liquid water management submodule, an outer package submodule and other parts. The distribution unit distributes the hydrogen, air and a cooling medium which enter the modules into each stack; the power management unit carries out state detection and management on the modules and controls the connection and disconnection of power output; the voltage reducing and heating submodule regulates the temperature of the fuel cell stack and controls the output voltage; the liquid water management submodule separates liquid water from the hydrogen and the air which enter the fuel cell stack module and discharges the liquid water at the hydrogen side; and the outer package submodule realizes waterproof and dustproof and heat preservation of the fuel cell stack module and discharges the hydrogen and steam in the package module. One advantage of the invention is that the fuel cell module can rapidly enter an ideal working state, thereby being beneficial to improving the performance, stability, safety and the like of the fuel cell module.

Description

Technical field [0001] The invention belongs to the field of fuel cells, and particularly relates to fuel cell modules. Background technique [0002] A traditional fuel cell module usually only includes a fuel cell stack, a hydrogen distribution unit, an air distribution unit, a cooling medium distribution unit, a single cell voltage detection unit, and a power output unit. The disadvantage of the traditional fuel cell module is that the module does not have the function of water and heat management, which is not conducive to entering the ideal working state as soon as possible when the fuel cell is in use. Summary of the invention [0003] The purpose of the present invention is to provide a fuel cell module structure with hydrothermal self-management capability, so that the fuel cell module can quickly enter an ideal working state. [0004] The technical solution of the present invention is: a fuel cell module with water and heat management capabilities, including a fuel cell sta...
