Description
Technical field
The present invention relates to a kind of monomer battery voltage monitoring field, in particular to connector, monitoring device and method that a kind of fuel cell pack monomer battery voltage is monitored, the voltage that wherein said method is particularly suitable for the every described cell of the fuel cell pack to the cell comprising greater number is monitored.
Background technology
Fuel cell (FuelCell) is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that the chemical energy had by fuel cell is directly transformed into electric energy, its structure composition is roughly the same with general battery, specifically, the monomer of fuel cell is made up of positive and negative two electrodes and electrolyte equally, unlike, positive and negative two electrodes of fuel cell itself do not comprise active material, but when operation of fuel cells, fuel and oxidant are supplied in outside, and react in the inside of fuel cell, thus, produce electric energy.
Proton Exchange Membrane Fuel Cells is the one of fuel cell, the principle of its work is that hydrogen forms proton and electronics at positive electrode by cracking, wherein proton permeability dielectric film is to negative electrode and hydrogen and be combined by the electronics of external circuit and produce electric energy, and single step reaction of going forward side by side generates water.Because the emission of fuel cell is only pure water, do not pollute the environment, therefore, fuel cell is one of important directions of battery development from now on certainly.
Under normal circumstances, it is lower that the operating voltage of cell generally all sets, as about 0.6V-0.7V, therefore, in the actual application of fuel cell, multiple cell is usually needed to form fuel cell pack by the mode of series connection, thus, make fuel cell pack have larger power.
Pile up stability in the process of work and reliability in order to ensure fuel cell, need the voltage of each cell to fuel cell pack to monitor, the mode of monitoring is generally inspection type.Specifically, suppose that fuel cell pack is formed by the series connection of n cell (cell), in the process of monitoring, need from cell.1, cell.2, cell.3 ... each cell of cell.n is monitored, and calculate the potential difference V of neighboring unit cell, the method wherein calculating potential difference V is: V.1=V (cell.1)-V (cell.2), V.2=V (cell.2)-V (cell.3) ..., calculate magnitude of voltage V.1-V.n successively.This magnitude of voltage can be used for reflecting that fuel cell piles up the situation of change of voltage with power output of cell in running, thus, reflect the behavior pattern of battery pile.Meanwhile, this magnitude of voltage also can reflect the gas leakage of battery pile inside and outside portion indirectly, the indexs such as air quantity adjustment, and therefore, the test of magnitude of voltage is for the operation important role of fuel cell pack.

Traditionally, the monomer of fuel cell pack is connected on circuit board by the mode that usual use test folder or test hook, when the number of the cell of fuel cell pack is less, adopt dismantle in this way efficient and convenient, safe and reliable, and test clip or test hook and can also adapt to dissimilar fuel cell pack, have stronger versatility.But, along with the increase of the cell number of fuel cell pack, the mode that this employing test clip or test hook not only dismounting wastes time and energy, it is too tight that each test clip or test hook arrangement, after test clip or test hook are installed to fuel cell pack, if the problem that some test clips or test are ticked existing loose contact or come off, monitoring personnel can be difficult to the place finding this problem, and, even if after pinpointing the problems, also be difficult to repair it, to such an extent as to cause larger error to monitoring result or cause monitoring to complete normally.
In addition, along with the increase of the number of monomers of fuel cell pack, hook for the test clip that connects or test and also will take larger space, for the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of compactedness, traditional this mode cannot be suitable for.
