Fuel cell technology has the advantages of environmental protection, high energy efficiency, long range, etc. It is mostly used in cargo and large buses, which requires high safety and reliability. For this reason, the country has successively formulated the monolithic electric stack of hydrogen fuel cell and the corresponding engine testing standards and regulations, aiming to provide a strong guarantee for the application and promotion of fuel cell technology by strengthening the work of professional and standardized testing of hydrogen fuel cells.

High power feed-back DC electronic load ANEL series with power 1000KW and current 2000A, with high performance full power section energy feed-back function to the grid. High control accuracy, fast response speed, optimized bi-directional DCDC conversion technology, wider DC input voltage range, can achieve the full range of input from 0V to full scale. It is mainly used for testing the voltage and current of fuel cell monoliths and power stacks. The programmable bi-directional DC power supply ANEVH series provides high stability voltage and current output for fuel cell compressor testing, with output voltage range of 0-2250V and single power of 30KW to meet the high power output demand of fuel cell compressor. It mainly verifies the response time, power regulation capability and overload capability of fuel cell air compressor. Wide range programmable DC power supply AN53 series with voltage 0-2250V, single machine provides 15KW output power, high factor, fast dynamic response, low ripple output, high power density. With the outstanding performance of constant power and wide range output, it provides stable voltage and current output for hydrogen circulation pump testing.
