Description
Technical field:
The present invention relates to the fuel cell technology field, particularly the temperature control technology of fuel cell.
Background technology:
Fuel cell piles up that output performance differs greatly under the different temperatures, so fuel cell wishes that after starting it works as early as possible to optimum temperature range, in the prior art, usually the way that adopts is to utilize the flow path of thermostat control cooling fluid, when fuel battery temperature is low, cooling fluid does not flow through radiator, to improve the programming rate of fuel cell.Its deficiency is: in the practical application, fuel cell generation is subjected to the restriction in space, and in the distributed arrangement occasion, as fuel-cell car, water pump and thermostat are far away from the galvanic pile module distance usually, and it is slower to cause pile to heat up.
Summary of the invention
The objective of the invention is to propose a kind of inner heat cycles fuel cell module, to solve the deficiencies in the prior art.Technical scheme of the present invention is: a kind of inner heat cycles fuel cell module, comprise fuel battery stack module and module-external cooling recirculation system, the module-external cooling recirculation system is connected with the Inlet and outlet water passage of the cooling water system of the fuel cell pack of fuel battery stack module inside by the turnover pipeline, the inside that it is characterized in that described fuel battery stack module also is provided with micro pump, threeway, unidirectional valve and control unit, two threeways are connected on the intake tunnel and exhalant canal of cooling water system of fuel cell pack, unidirectional valve is connected on the channel attached passage of Inlet and outlet water of cooling water system of fuel cell pack of the turnover pipeline of threeway and module-external cooling recirculation system and fuel battery stack module inside, the 3rd interface that is connected the threeway on the intake tunnel of cooling water system of fuel cell pack is connected with the delivery port of micro pump, the 3rd interface that is connected the threeway on the exhalant canal of cooling water system of fuel cell pack is connected with the water inlet of micro pump, control unit is electrically connected with the control switch of micro pump, is connected with holding wire with the temperature-detecting device of fuel cell pack.
The control method of a kind of inner heat cycles fuel cell module of the present invention, the temperature-detecting device that it is characterized in that described control unit fuel cell heap detects the temperature T of fuel cell pack and in real time according to the switch of the control temperature control micro pump of setting: the temperature T that detects fuel cell pack when the temperature-detecting device of control unit by fuel cell pack is when setting control temperature T set, the control micro pump is opened, and cooling water circulates in inside modules; The temperature T that detects fuel cell pack when the temperature-detecting device of control unit by fuel cell pack is when setting control temperature T set, and the control micro pump is closed, and the cooling water system of fuel cell pack and module-external cooling recirculation system circulate.
The invention has the beneficial effects as follows: realize the isolation of inside modules circulation and external refrigeration circulation, can make the fuel cell module optimum temperature service area that evenly is rapidly heated; Have realize simple, cost is low and the simple advantage of system configuration.
