Tech Talk - Cathode Air Blower - Air Compressor - Fuel Cell Technology - Hyfindr Franzbäcker

Learn about the cathode air blowers for stationary fuel cells from experienced engineers in the hydrogen economy. In this conversation between Steven and Marc, they discuss air blowers, specifically cathode blowers. They discuss the difference between blowers and compressors, explaining that there is no hard definition for either term, but that compressors are primarily used to compress air, while blowers create a certain flow. There are different types of blowers, including the claw compressor, which uses rotating claws to generate a flow or compression, and the turbo blower, which uses centrifugal forces to create pressure. The cathode air blower on the table in this Tech Talk is a side channel blower, which uses blades on the impeller to generate pressure on the cathode side of a fuel cell. Also, this Tech Talk highlights the importance of efficiency in blowers for fuel cells, as they are a parasitic load, and explains that it uses a permanent magnet motor and a high-efficiency compression chamber.

Executive Summary of Tech Talk Script:
Hyfindr Tech Talks is a video series focusing on understanding the technology that makes the hydrogen economy work. In this episode, Steven hosts Hyfindr Tech Talks and Marc, a guest who has been working on air blowers for stationary fuel cells for years. Marc presents the second generation of their small side channel blowers that can be used as a cathode blower for stationary fuel cells, which is small, modular, contactless, oil-free, and frequency controlled, and can even replace mass flow meters in the fuel cell. The compressor's main purpose is to compress air, while the blower creates a certain flow. Both terms are used interchangeably for side channel or turbo blowers or compressors.
There are different kinds of air blowers for the cathode side, including a claw compressor, which generates a certain flow or compression by having two rotating claws. The second possibility is a turbo blower that generates a certain pressure level depending on the diameter of the pump and speed, while the third possibility is a side channel blower. The side channel blower has blades on the impeller that generate a pressure used on the cathode side of a fuel cell.
Overall, the conversation focuses on understanding the technology behind air blowers and their applications in the hydrogen economy.
