Towards a carbon free society the IHI group is committed to provide products, technologies and services in line with ecological and economical sustainability. Storage and transportation of green energy are major challenges related to the global transition from fossil fuels towards 100% renewables. IHI is active in various areas ranging from SOFC technology via ammonia combustion to smart community demonstrator projects. With respect to mobility hydrogen fuel cell technology is identified as one major pillar for CO2-neutral vehicular propulsion – especially for higher payloads and extended driving distances. Since more than 20 years IHI is providing charging systems for stationary fuel cell applications and since 2004 also for mobile fuel cell applications.
IHI´s oil free turbocharger for fuel cell applications is providing state-of-the-art boosting technology to enable emission free propulsion systems. It comprises a turbine, a compressor and, on the same shaft, an electric motor as well as air foil bearings to support the rotor. The turbine utilizes the enthalpy from the stack exhaust to lower the required electric power for driving the compressor. It can provide up to 40% of the needed compressor power and hence substantially increases the system efficiency. Compressor and turbine are optimized for operating conditions in fuel cell systems regarding specified airflow and pressure ratio, which is typically in the range of 3.0.
