The fuel-cell control unit (FCCU) holds significant importance withinfuel-cell electric vehicle drivetrainsubsystems as it is responsible for the overall process control of the entire fuel-cell system. Its responsibilities encompass supervising hydrogen and air processing, thermal and water management, ...
The fuel-cell DC-DC boost converter is an essential component in the functioning offuel-cell electric vehicle drivetrain systems. In a fuel-cell electric drivetrain system, there is typically at least one DC-DC boost converter that connects the fuel-cell stack to the DC link voltage of thetra...
Fuel Cell In subject area: Engineering Fuel cell (FC) is an electrochemical system that converts the chemical energy from the reaction of a fuel (usually hydrogen) and an oxidant (usually oxygen in ambient air) directly into electricity with high efficiency and high environment compatibility. From...
2.3.2 Fuel cell electric vehicle (FCEV) Similar to BEV, fuel cell electric vehicles (FCEVs) use an all-electric powertrain; however the energy source is a fuel cell stack. An FCEV is fueled with hydrogen, thus emits only water and heat. There is no tailpipe pollutant, thus it is recog...
According to the ultimate cost target of US$30 kW−1 for the fuel cell stack3, the Pt loading in the catalyst layers must be below 0.125 mg cm−2 (ref. 4). However, as the Pt loading decreases, the oxygen transfer resistance increases because of the limited accessible active...
