Abstract
The present invention provides a kind of fuel cell pack water flow passage, including an import, the runner of multiple parallel connection and an outlet, current enter described fuel cell pack water flow passage from described import, described import connects with one end of the runner of multiple parallel connections, current are further separated into the runner of multiple parallel connection from described import, the other end of the runner of multiple parallel connections and outlet, current flow out from described outlet, described import, the runner of multiple parallel connection and go out interruption-forming water-flowing path.It is an advantage of the current invention that fuel cell pack water flow passage is communicated by multiple runner parallel connections, current enter pile and circulate from multiple runners after import shunts simultaneously, and flow out from outlet.This solution solves usual state place an order into the water flow passage water-cooled singly gone out do not reach cooling require situation, whole water route is all the cooling system of battery pile, is effectively taken away by the waste heat of the generation in electrochemical reaction.
Description
Technical field
The present invention relates to fuel cell field, particularly relate to a kind of fuel cell pack water flow passage.
Background technology
Proton Exchange Membrane Fuel Cells has that operating temperature is low, it is fast to start, specific power height, simple in construction, the advantage such as easy to operate, be acknowledged as the first-selected energy at electric automobile, stationary power generation station etc..At fuel battery inside, migration and conveying that PEM is proton provide runner so that proton arrives negative electrode through film from anode, constitutes loop with the electron transfer of external circuit, outwardly provides electric current.The efficiency of Proton Exchange Membrane Fuel Cells is usually less than 50%, produces so having substantial amounts of used heat while generating.How to carry out good heat conduction, become industry focus of attention.
Owing to heat conductivity and the specific heat of air are the least, when the power of Proton Exchange Membrane Fuel Cells is more than 10KW, air cooling can not meet the cooling requirement of system, at this time circulating water is best mode, how to design water flow passage so that it is it is current urgent problem that good cooling results and efficiency improve.
Summary of the invention
The technical problem to be solved is to provide a kind of fuel cell pack water flow passage, and it can improve cooling effectiveness, it is thus achieved that good cooling effect.
In order to solve the problems referred to above, the invention provides a kind of fuel cell pack water flow passage, including an import, the runner of multiple parallel connection and an outlet, current enter described fuel cell pack water flow passage from described import, described import connects with one end of the runner of multiple parallel connections, and current are further separated into the runner of multiple parallel connection, the other end of the runner of multiple parallel connections and outlet from described import, described current flow out from described outlet, described import, the runner of multiple parallel connection and go out interruption-forming water-flowing path.
Further, described fuel cell pack water flow passage includes five runners in parallel.
Further, described import includes multiple points of imports, and each point of import and some flow passage, to direct water in each described runner.
Further, described outlet farther includes multiple mouth that separates, and each separates mouth and some flow passage, to be derived in each runner by water.
It is an advantage of the current invention that fuel cell pack water flow passage is communicated by multiple runner parallel connections, current enter pile and circulate from multiple runners after import shunts simultaneously, and flow out from outlet.This solution solves usual state place an order into the water flow passage water-cooled singly gone out do not reach cooling require situation, whole water route is all the cooling system of battery pile, is effectively taken away by the waste heat of the generation in electrochemical reaction.
Accompanying drawing explanation
Fig. 1 is the lateral structural representation sketch of fuel cell pack water flow passage of the present invention；
Fig. 2 is that the E-E of Fig. 1 is to cross section simplified schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the fuel cell pack water flow passage that the present invention provides is elaborated.Accompanying drawing of the present invention only symbolically illustrates the structure diagram of fuel cell pack water flow passage of the present invention, only explains the present invention, does not represent the practical structures of fuel cell pack water flow passage.
Seeing Fig. 1 and Fig. 2, one fuel cell pack water flow passage of the present invention, including an import 1, the runner 2 of multiple parallel connection and an outlet 3, water (flow) direction is as shown by arrows in FIG..
Current enter described fuel cell pack water flow passage from described import 1.Described import 1 connects with one end of the runner 2 of multiple parallel connections, so that current are further separated into each described runner 2 by after import 1.In this embodiment, described fuel cell pack water flow passage includes five runners 2 in parallel, and runner quantity of the present invention is not limited to this.
In this embodiment, described import 1 is only an import, and all current enter described fuel cell pack water flow passage by this import 1, and are further separated into each described runner 2.In other detailed description of the invention, described import 1 can include multiple points of imports, and each point of import can connect with some runners 2, to be entered in each described runner 2 by moisture conductance.
The other end of the runner 2 of multiple parallel connections connects with outlet 3, and described current flow out from described outlet 3.Described import 1, the runner 2 of multiple parallel connection and outlet 3 formation water-flowing path, to realize the cooling to described fuel cell pack.
In this embodiment, described outlet 3 is only an outlet, and all current are by, after multiple runners 2, flowing out described fuel cell pack water flow passage from this outlet 3.In other detailed description of the invention, described outlet 3 can include multiple mouth that separates, and each mouth that separates can connect with some runners 2, to be derived in each runner 2 by water.
Fuel cell pack water flow passage is communicated by multiple runner parallel connections, and current enter pile and circulate from multiple runners after import shunts simultaneously, and flows out from outlet.This solution solves usual state place an order into the water flow passage water-cooled singly gone out do not reach cooling require situation, whole water route is all the cooling system of battery pile, is effectively taken away by the waste heat of the generation in electrochemical reaction.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
