Amount.
The three-in-one detection means of the fuel cell further comprises tracheae switch valve, two five-way valve hand-operated valves, fuel electricity
The three-in-one detection means in pond needs to be put into environmental simulation chamber when carrying out bulk resistor detection, and data acquisition module can gather high accuracy
Digimatic micrometer and high-precision desk-top universal meter data.
The course of work of the present embodiment is specific as follows：
When carrying out the detection of fuel cell key components and parts bulk resistor and compression ratio measurement, by upper sealing block 6 and lower sealing block 5
Dismantle and the three-in-one detection means of fuel cell is put into environmental simulation chamber.It is now that parts to be measured are placed on lower conductor by size
The sample deposition of plate 3, high-precision desk-top universal meter and DC power supply terminal are connected through a screw thread supreme conductor plate 8 respectively
With lower conductor plate 3, then tracheae switch valve is opened, gases at high pressure pass sequentially through pressure regulator valve, high-precision digital-display air pressure table, two
Cylinder 10 is passed through after the logical hand-operated valve in position five, choke valve.Now change (rigid connection by observing the registration of high-precision desk-top universal meter
Registration mutation bounce when touching) the regulation pressure regulator valve pressure that makes cylinder 10 be acted on by the briquetting 7 that exerts a force on testing sample is 0PSI
(i.e. upper conductor plate 8 and lower conductor plate 3 just touches with testing sample rigid connection), now resets high-precision digital display dial gauge 12,
Regulation dc source for preset value (such as 5A) and opens data acquisition module by the electric current of testing sample.Then pressure regulation is adjusted
The pressure that valve to certain air pressure makes cylinder 10 be acted on by the briquetting 7 that exerts a force on testing sample is preset value (such as 100PSI),
Now data of the high-precision digital display dial gauge 12 of data acquisition module automatic data collection and high-precision desk-top universal meter and automatic
Preserve to computer, holding acts on corresponding pressure value on testing sample and do not fade to the long enough time, according to high-precision
The data and Ohm's law of formula universal meter can calculate the bulk resistor of part to be measured, according to the data of high-precision digital-display amesdial 12
Change can calculate the compression ratio of testing sample.

Property measurement pipeline enter upper sealing block 6 quick connector air pressure preset time (such as 2h) in it is constant, now record high accuracy
Digital-display air pressure table registration, when gas tank volume is 1L, pass through calculation formula(wherein P1 is gas
Pressure values before transmission measurement in gas tank, P2 are the pressure values in gas tank after the setting time t that gas permeation rate is tested,
Vm is the molal volume of gas under normal temperature and pressure, and Vm=22.4L/mol, T are system temperature, unit K.R is gas constant (ratio
Constant) unit is J/ (molK), S is the area of testing sample, and unit CM2, t are the setting time of gas permeation rate test,
Unit is the second.C is gas permeation rate, and unit is every square centimeter per second, the i.e. L/ (cm2*s) of liter) testing sample list can be calculated
The gas permeation rate of position chronomere area, high-precision digital-display air pressure table on gas tank need to be only observed when need to only detect air-tightness
Whether change can judgement sample air-tightness.
The present embodiment at least has the following effects that：
