Fuel cell systems are a key element in the growing hydrogen economy. During periods of high demand, these systems can convert excess energy stored in the form of hydrogen back into electricity (re-electrification). Thus, they facilitate a flexible response to fluctuating electricity demands. However, this requires sufficient capacity from stationary energy generation systems based on fuel cells.
In commercially available stationary fuel cell systems, operation is controlled by model-based control loops. However, relevant system parameters are missing to guarantee full control, i.e., continuous performance monitoring. This is because cost-effective, long-term stable, and sufficiently accurate sensor systems capable of providing the necessary data are not yet commercially available. Consequently, the systems cannot realize their full potential in terms of efficiency and durability.
Our goal: Optimize operational management based on real-time data
The »EISBaEr« project is developing a sensor system that addresses these challenges. Innovative sensor approaches are being researched for measuring hydrogen concentration, humidity, and other relevant parameters, as well as robust sensor housings. The novel sensor system will then be built and tested in a fuel cell system.
The new control system, based on real-time data, aims to optimize the operation of stationary fuel cell systems in terms of performance, efficiency, reliability, and service life. This should allow for more dynamic load changes and increase operational safety.
