#12 – Hyfindr Tech Talks – Fuel Cell DC-DC Converter Design and Future | Thomas Vetter – Aradex

What’s the future of DC-DC converters in the hydrogen industry?

In this episode of Hyfindr Tech Talks, Thomas Vetter (Aradex) joins Steven Oji (Hyfindr) to discuss the use, design, and future of DC-DC converters in fuel cell systems. They explain why these converters are essential to adapt the fuel cell's direct current voltage to a vehicle's high-voltage system, and the crucial role they play in the transition to higher system voltages (e.g., in trucks) which allows for smaller, lighter, and cheaper cables.

You’ll learn about:

• Why step-up DC-DC converters are needed for fuel cell technology.

• The working principles and components of fuel cell DC-DC converters.

• Challenges related to increasing the step-up ratio to meet higher target voltages.

• The impact of switching frequency on converter size and efficiency.

• Future developments in DC-DC converters, including the role of FPGA and Electro Impedance Spectroscopy (EIS).

This episode is perfect for engineers, researchers, and hydrogen professionals interested in power electronics, fuel cell system design, and the push towards higher voltage hydrogen applications.
