Collecting data for next projects
With over 30 sensors and another 30 active or passive components, a fuel cell system is a complex challenge for our team. This is where advanced control technology, thermodynamics and fluiddynamics meet. Due to the very specific requirements of a fuel cell, it is important to always operate the system at its optimal points.
Some of the most important components are described below:
Compressor with inverter
With a powerful compressor and a backpressure valve, the air is brought to the desired pressure before the fuel cell. The inverter supplies the compressor with the necessare high-voltage power.
Air filter and hoses
An air filter is used to protect the fuel cell from pollutants. The air piping consists of flexible hoses, which, depending on the mechanical connections of the components, must be completed with transition parts. The hoses are attached to the components with hose clamps.
Over 30 sensors monitor and control our system in order to record or further process all measurement variables. Precise sensor data is also required for the complex control of the system. The measured variables include pressure, temperature, mass flow, humidity and conductivity.
Due to the low efficiency of fuel cells, almost half of the energy in hydrogen is converted into heat. Therefore, our system has to be cooled by a pump and an efficient heat exchanger. Depending on the required cooling capacity, the pump can be operated at the optimal control point.
Software and controls
A self-designed main control unit, together with an extension module and a Raspberry Pi, takes over the measurement, storage and further processing of the sensor data. Almost 20 different actuators are controlled on the main control unit. All the data can be displayed in various diagrams and monitored at any time via web interface.
