Description
Technical field
The utility model belongs to fuel cell field, relates in particular to Proton Exchange Membrane Fuel Cells packing module.
Background technology
Proton Exchange Membrane Fuel Cells can be used as the power set of car, ship.The working method and the internal combustion engine of engine that with the Proton Exchange Membrane Fuel Cells is power set is similar, must continuously send into battery to hydrogen fuel and oxidant, and discharges reaction product water and certain used heat continuously to keep the balance of battery material and heat.
Car, marine fuel battery packages shell water proof and dust proof will reach IP55 usually, even higher, and in order to reach the water proof and dust proof requirement, existing fuel cell is that fuel cell is packaged in the airtight housing, and the environment of operation of fuel cells is enclosed.The deficiency of existing fuel cell packing module is: during operation of fuel cells, hydrogen fuel has small leakage sometimes and scurries in the housing of fuel cell packing module.Fuel cell packing module memory has hydrogen can be related to the security of operation of fuel cell.The packaging shell of existing fuel cell packing module seals, and can't get rid of the hydrogen in the packaging shell.
Summary of the invention
The purpose of this utility model is a kind of system that can guarantee hydric safe in the fuel cell packing module of design.Technical scheme of the present invention is: a kind of system that improves hydric safe in the fuel cell packing module, the air system and the fuel cell module that comprise fuel cell system, air system comprises air filter, blower fan, air tail row and humid enthalpy conversion equipment, the air outlet slit of air filter connects the inlet of blower fan with the main line pipeline, the outlet of blower fan connects the fresh air inlet of humid enthalpy conversion equipment with the main line pipeline, the fresh air outlet of humid enthalpy conversion equipment connects the air intake of fuel cell with the main line pipeline, the air outlet slit of fuel cell connects the waste and old air intlet of humid enthalpy conversion equipment with the main line pipeline, fuel cell module comprises the packaging shell of fuel cell and airtight package fuel cell, its structure is to offer air inlet and gas outlet on the packaging shell of described fuel cell packing module, air inlet on the housing of fuel cell packing module is communicated with tap line with the air outlet slit of blower fan, and the gas outlet on the housing of fuel cell packing module is communicated with tap line with the air intake of blower fan.
A kind of system that improves hydric safe in the fuel cell packing module described in the utility model, its structure is that the air inlet on the packaging shell of described fuel cell packing module is connected by tee pipe fitting on the pipeline between the fresh air inlet of the air outlet slit of blower fan and humid enthalpy conversion equipment, and the gas outlet on the packaging shell of described fuel cell packing module is connected by tee pipe fitting on the pipeline between the air intake of the outlet of air filter and blower fan.
A kind of system that improves hydric safe in the fuel cell packing module described in the utility model, its structure is that the air inlet on the packaging shell of described fuel cell packing module is opened in the bottom or the side of packaging shell, and the gas outlet is opened in the top or the side of packaging shell.
A kind of system that improves hydric safe in the fuel cell packing module described in the utility model, its structure is the caliber of the caliber of described tap line less than the main line pipeline, and the ratio of the caliber of the caliber of tap line and main line pipeline is between 1: 1.5～1: 15.
Workflow of the present utility model is: during blower fan work, the dry air that blower fan is sent is divided into two-way: the one tunnel enters fuel cell behind humid enthalpy conversion equipment humidification, and the air inlet of another road on fuel cell packing housing directly enters in the fuel cell packing housing.Because humid enthalpy conversion equipment air inlet is bigger than the caliber of fuel cell seal shell air inlet, most of air enters the humid enthalpy conversion equipment and enter fuel cell again behind humid enthalpy conversion equipment humidification, the humid enthalpy conversion equipment is come out to enter from fuel cell in the reaction back, enters atmosphere at last.Another fraction air enters fuel cell packing housing by the fuel cell seal shell air inlet, because there is a negative pressuren zone in the air intake place of blower fan, after entering dry air in the fuel cell packing module housing and in housing, circulating, the hydrogen that leaks out from fuel cell that carries in the housing is discharged from the gas outlet on the fuel cell packing housing, and enter blower fan with the fresh air of sending by air filter, after the blower fan supercharging, send again, the air of sending repeats the branch two-way and enters respectively in fuel cell and the fuel cell packing module housing, discharge by air tail row after entering the air reaction of fuel cell, tail row's air will be taken hydrogen wherein out of, and the density of hydrogen in the fuel cell packing module housing is reduced.This process is constantly carried out with the blower fan running all the time.
The utility model has the advantages that: owing on the packing module housing of fuel cell, offered air inlet that is communicated with the air outlet slit of blower fan and the gas outlet that is communicated with the air intake of blower fan, just in case hydrogen gas leakage is arranged, can make the hydrogen partial of scurrying in the fuel cell packing module housing, under the effect of blower fan, constantly discharge the packing module, thereby guarantee that the interior density of hydrogen of fuel cell packing module housing does not influence the safe operation of fuel cell with air flows.
