Fuel Cell Test Cooling System

A hydrogen fuel cell engine is a power generation device that directly converts hydrogen and oxygen into electrical energy through an electrochemical reaction.
The working process does not involve combustion, no mechanical loss, high energy conversion rate, the product is only electricity, heat and water, the operation is stable and the noise is low.Known as the "ultimate environmentally friendly engine".
The hydrogen fuel cell engine is composed of six components: a stack, a hydrogen supply circulation system, an air supply system, a water and heat management system, an electronic control system, and a data acquisition system.


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.


Multi-channel temperature and flow control, one device can realize multi-channel output, and each channel can control different flow;
The device can choose not only to control the flow, but also to control the pressure;
At the same time, it is equipped with a powerful circulation pump to ensure the delivery of high-viscosity liquids and can provide a high flow rate under stable pressure
