Fuel Cell Test Cooling System
Product Description
The hydrogen fuel cell test cooling system can provide a stable test platform for fuel cell engines.
It is dedicated to the performance test of vehicle fuel cell engines. It consists of hydrogen supply system, load system, motor drive system, control system, safety system, etc.
The high-pressure hydrogen system supplies hydrogen to the fuel cell engine.
The engine outputs electrical energy, which is converted into rotary mechanical energy by a DC / DC converter and a motor to drive the dynamometer.
The dynamometer is both a load and a dynamic measurement device.

The whole system is a fully enclosed system. There is no oil mist at high temperature, and low temperature does not absorb moisture in the air. The system does not increase the pressure due to high temperature during operation, and the heat medium is automatically replenished at low temperature. | |||||||
