The Engineer, a British publication, reports on a turbocharger for fuel cells. Because a fuel cell is a cross between a combustion engine and an electric motor, the concept of pushing extra air through the fuel cell to increase power is similar to that of turbocharging a regular two- or four-stroke engine. The publication says this could double the output of a hydrogen fuel cell. Like other combustion engines, a fuel cell can be limited by the airflow entering, that supply limiting their ability to release positively-charged hydrogen ions. Bryn Richards, CEO of Aeristech, explains, “Our proprietary high speed motor and control technology allows us to deliver air at a much higher pressure [than existing systems]. No other motor control arrangement is able to deliver at this pressure with such a high efficiency.” Without a lot of detailed information from Aeristech, The Engineer suggests the system uses a “sophisticated control system capable of maintaining a very consisten torque output.
