Tech Talk - Fuel Cell DC DC Converter - Hydrogen Technology Explained - Hyfindr Vetter

Learn about the use and design of fuel cell DC-DC converters that are used in the hydrogen industry. Steven and Thomas in this Hyfindr Tech Talk are discussing the importance and future of the DC-DC converter for fuel cell technology. DC-DC converters are necessary to adapt the fuel cell voltage to the high-voltage system, as fuel cells produce direct current. They also discuss the trend towards higher voltages, which allows for the use of smaller, cheaper, and lighter cables. The step-up ratio of DC-DC converters needs to increase to handle the lower input voltage from fuel cells and higher target voltage. This is important for the design of fuel cell systems in large vehicles like trucks. #hydrogen #fuelcell #engineers #engineering #technology #tech #brennstoffzelle #dcdcconverters #dcdc #fuelcellconverters Jump right into the discussion topics: 0:00 Hyfindr Tech Talk 0:36 Welcome, Thomas Vetter 0:48 What did you bring?

He explained that while AC grids typically use a transformer to adjust voltage levels, DC voltage from fuel cells cannot be transformed in the same way. Instead, DC/DC converters are used to shift voltage up or down to the necessary levels. The trend of the market is explained that as battery voltage requirements increase, there is a trend in the market towards higher voltage levels. This is due to the fact that higher voltage reduces the need for large, heavy cables, which are costly to manufacture and difficult to maneuver. For example, trucks require large, thick cables for a 600 V battery, while an 850 V battery would require much smaller cables. The challenges of increasing step-up ratios in DC-DC converters, as the incoming voltage from fuel cells decreases while target voltage increases are also deeply discussed. This requires a higher step-up ratio, but the size of the converter cannot increase. In the end, the future of DC-DC converters in the fuel cell industry is discussed, and how it will integrate with fuel cell and change the approach of innovation in this industry.
