Fluidic solutions for stationary fuel cell technology
Stationary fuel cells such as the solid oxide fuel cell (SOFC) or the proton exchange membrane fuel cell (PEMFC) efficiently convert chemical energy from hydrogen into electrical energy and are used as reliable energy sources in various applications, including buildings and ships. Reformer systems are used so that fuel gases or fuels can also be used as media instead of pure hydrogen. In stationary fuel cells, fluidics – i.e. the management of gas and liquid flows – is an important aspect in ensuring efficient and reliable power generation.
As a fluidics expert, Bürkert is the ideal partner to guide you through these complexities. See for yourself!
What is important in fluidic control, and how does it help with issues such as safety and increasing the efficiency of stationary fuel cells?
Using fuel cells to generate power and heat in buildings or on ships requires fuel gases to be handled safely. Air and gas control in stationary fuel cells therefore requires precise control for maximum efficiency. The components used must be suitable for the necessary safety and comply with national approvals. Energy-efficient and material-compliant solutions are required to guarantee optimum overall efficiency and the durability of the fuel cell.
Bürkert solutions impress users with their low power consumption and durability. The high number of switching cycles and long maintenance intervals contribute to the efficient utilisation of the stationary fuel cell. Our products are suitable for use with fuel gases, as well as being ready for future use with hydrogen and possessing the necessary approvals.
Bürkert expertise in stationary fuel cells
Careful planning and control of the fluidics in stationary fuel cells is crucial for maximising efficiency, extending service life and ensuring reliability. The exact design of the fluidics can vary depending on the fuel cell technology (e.g. PEMFC, SOFC) and application.
Safe shut-off of fuel gas or hydrogen
The safe shut-off of fuel gases or hydrogen is a critical function for stationary fuel cells. The precise control and reliable shut-off mechanisms of our valves not only ensure the reliable operation of the fuel cell, but also contribute greatly to the safety and stability of the entire fuel cell system. This is particularly important for minimising potential risks such as leaks or uncontrolled gas release and therefore enabling smooth and safe operation in various stationary applications. This ensures compliance with legal regulations and safety standards.
