Embodiment Construction

[0032] The embodiment is a 40kw fuel cell module with hydrothermal management capabilities.

[0033] There are two 20kw fuel cell stacks, each has 150 sections, the operating pressure is less than 100kpa, the decay rate Vt is 10mV / h, the air side resistance index is 20kpa50Nm3 / h, the hydrogen side resistance index is 25kpa10Nm3 / h .

[0034] The air circuit, hydrogen circuit and cooling medium circuit are connected in parallel, and the power output is connected in parallel, such as Picture 9 As shown, 1001 and 1002 are fuel cell stacks. The fuel cell stack 1001 air inlet 2301 is connected to the fuel cell stack 1002 air path inlet 2302 through the air distribution unit 230, and the fuel cell stack 1001 air outlet 2303 is connected to the fuel cell through the air distribution unit 230 The stack 1002 air path outlet 2304 is connected, the fuel cell stack 1001 hydrogen inlet 3301 is connected to the fuel cell stack 1002 hydrogen path inlet 3302 through the hydrogen distribution unit 3...

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...
