ZF introduces hydrogen component at the IAA
The highly efficient system extracts excess hydrogen from the fuel cell system and feeds it back into the circuit. The hydrogen recirculation blower works together with the high-speed air compressor from ZF. The latter supplies the fuel cell stack with air in order to optimise the chemical reaction between hydrogen and oxygen.
“ZF has applied its extensive expertise in system integration and air bearing systems to develop these innovative products,” explained Dr Christian Brenneke, Head of Innovation & Development at ZF’s Commercial Vehicle Solutions Division. “The newly unveiled Hydrogen Recirculation Blower, combined with our fuel cell air compressor, is part of our expanding full-flex e-mobility portfolio. These innovations demonstrate how our products for fuel cell systems are driving decarbonization in a technologically open manner alongside our growing range of decarbonized technologies.”
The hydrogen recirculation blower is compact, lightweight and optimised for efficiency. Its high-speed turbo can reach up to 100,000 revolutions per minute and utilises air-bearing technology. This reduces the need for lubrication and prevents contamination of the fuel cell stack. According to the company, this ensures optimum efficiency and high mass flow rates in the long term.
