Fuel cell module with water and thermal management capability

Abstract

The invention discloses a fuel cell module with water and thermal management capacity, comprising a fuel cell pile, a distribution unit, a power management unit, a voltage reducing and heating submodule, a liquid water management submodule, an external packing submodule and other parts. The distribution unit distributes hydrogen, air and a cooling medium which enter the modules into each single pile; the power management unit carries out state detection and management on the modules and controls the connection and the disconnection of power output; the voltage reducing and heating submodule regulates the temperature of the fuel cell pile and controls the output voltage; the liquid water management submodule carries out liquid water separation on the hydrogen and the air which enter a fuelcell pile module and discharges the liquid water at the hydrogen side; and the external packing submodule realizes water and dust prevention and heat preservation of the fuel cell pile module and discharges the hydrogen and steam in a packing module. The invention has the advantages that the fuel cell module can rapidly enter the ideal working state, thereby being beneficial to improving the performance, the stability, the safety and the like of the fuel cell module.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to a fuel cell module. Background technique [0002] A traditional fuel cell module usually only includes a fuel cell stack, a hydrogen gas distribution unit, an air distribution unit, a cooling medium distribution unit, a cell voltage detection unit, and a power output unit. The disadvantage of the traditional fuel cell module is that there is no water and heat management function inside the module, which is not conducive to the fuel cell entering the ideal working state as soon as possible when it is in use. Contents 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 capability, including a fuel cell stack,...
