Guarantee the service life of temperature control mechanism 50.Simultaneously because need to first pass through humidification grid 40 in the air for entering temperature control mechanism 50,
And then guarantee the problem of can carrying out wet operations to air when being air-dried, prevent air-cooled 10 internal check of pile,
And then the working performance of air-cooled pile 10 is effectively guaranteed, the service life of single unit system is improved, and due to gas-water separation
Part 30 is connect by outlet pipe 34 with humidification grid 40, and the water that reaction is generated enters air-cooled pile 10 by 40 pairs of grid of humidification
Air humidified again, save humidification cost.
Above-mentioned temperature control mechanism 50 realizes the change to ambient enviroment heat, and by setting by the way that temperature adjustment part 60 is arranged
Radiating block 70 and lower radiating block 80 improve the contact area with ambient enviroment, and then by the temperature adjustment part 60 to ambient temperature
It is adjusted；And since temperature adjustment part 60 is semiconductor chilling plate, it only need to control energization and ring around can be adjusted in current direction
Border temperature facilitates operation.The above-mentioned fuel cell 100 with temperature control mechanism, by the way that temperature control mechanism 50 is arranged in air inlet, in turn
It realizes the adjustment to air-cooled 10 air themperature of pile is entered, solves requirement limitation of the fuel cell to environment temperature, greatly
The adaptability for improving fuel cell is conducive to the popularization of fuel cell；Through overtesting, subzero 10 DEG C in temperature, relative humidity
Under 10% natural environment, work one kilowatt fuel cell real output only three hectowatts or so under a normal environment,
It is only capable of playing 30% or so fuel battery performance, by installing the fuel cell 100 with temperature control mechanism additional, is consuming about
Under the premise of 90 watts of power, the real output of one kilowatt of fuel cell is promoted to normal condition, is greatly improved
The adaptability of fuel cell.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
