Late maintenance costs caused by human factors such as self-disassembly.

size of product

S 36 series of liquid cold hydrogen fuel cell hydrogen fuel cell stack mainly developed for small power application scenarios, mainly suitable for
24V, 48V, 78V, 145V application platform, is a suitable blower (low air pressure) and air compressor (high air pressure) gas supply of universal graphite stack,
and its unique long time resistance catalyst formula can avoid CVM control module for system integration.

The design discharge power range of S36 series reactor is 0-25 kW, discharge current is 0-290A, and supports 0-200 kPa

Working range of air source pressure. The company supports the design of any output power of the reactor customization, reactor size

With a length of 360mm and 69mm wide, the series thickness of the battery stack varies according to the required power, so refer to Table 1 and Table 2and table 3.

Table 1 Specification of high pneumatic reactor (hydrogen 140 kpa, air 130 kpa, water 68 ± 3℃, water 75 ± 3℃, 80% RH)

Table 2 Specification of low pressure reactor (hydrogen 60 kpa, air 40 kpa, water 68 ± 3℃, water 75 ± 3℃, 80% RH)

Note: The performance of the reactor is affected by many factors. The above is for reference only. If your requirements are not in the table, please contact the commercial department and relevant technical departments for selection and communication.

direction for use

PEMFC There are high requirements for the purity of hydrogen source, and there are also strict restrictions on the air source. The specific harmful or harmful PEMFC chemical components are not detailed and the proportion of the harm level, please consider and evaluate the relevant application environment.

The rated working medium pressure of S 36 series reactor is less than 220 kpa, the maximum hydrogen pressure is 150 kpa, the maximum air pressure is less than 140 kpa, and the maximum coolant pressure is less than 140 kpa. Its

In operation, 5 kpa<hydrogen pressure-air pressure <50 kpa, and 5 kpa <hydrogen-cold

However agent pressure<120 kpa.

The relative humidity range of the gas source required for the work of the reactor is 10% -90%. Ambient temperature-10-40℃, recommended relative

Humidity 30% -85%, ambient temperature 10-35℃.

The optimal thermal management conditions of the reactor are coolant inlet temperature 68 ± 3℃, coolant temperature outlet 75 ± 3℃,

For outlet temperature of coolant<80℃, recommended inlet temperature control 65℃ or outlet temperature control 72℃.

In order to make it play a better performance output, the recommended air measurement ratio is more than 2.2, the starting wind is recommended

The volume is greater than 1 / 4 of the rated demand wind volume, and it is not recommended to maintain the low wind volume and low wind speed for a long time.

The principle of the working medium of the reactor is "in and out on the air road" and "in and out".

The middle slot of the front and rear end plates has the positive / negative circle mark. Check whether the installation is correct before and after installation

And firm; reactor interface side with medium channel identification: A-air, C-coolant, H-hydrogen.

Air tightness detection

All the parameters have been tested before leaving the factory. It is necessary to carry out air tightness testing when the reactor is stored for a long time or not working for more than 6 months. If the reactor integrated power generation system is not started for more than 1 year, it is necessary to test the system or the reactor.

Single channel air tightness detection: the outlet of the detection channel and the other two access entrances are blocked, the outlet flow meter of the other two channels is connected, and the inert gas source series flow meter with stable pressure (50 kpa) is connected to be tested

Enter the channel, and record the data after a certain period of ventilation.

Unicom air tightness detection: all the exits of the three channels are blocked, and then the inert gas with stable pressure (200 kpa) is connected, and the data is recorded after a certain time.

The judgment standard of gas density data of each models are different, and the definition value can be different due to different use environment. Details can be consulted by the manufacturer.

Storage and maintenance

The reactor has been tested before leaving the factory, and there may be some water remaining inside, which is a normal phenomenon.

The recommended relative humidity is 50% -75%, and the ambient temperature is 25 ± 5℃. Such as the stack needs long-term storage, construction

The reactor conducts necessary periodic nitrogen purge and sealing during long-term storage.

conformally connected space
