Learn about the cathode air blowers for stationary fuel cells
Steven discusses with Marc about the second generation of 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.
