Commercialization of Fuel Cell power plants for the transportation industry will only be viable when the total system life cycle and operational costs are competitive with conventional alternatives. The component cost is driven by the vehicle application and subsystem stringent requirements while the system architecture and design can reduce the component cost by either size reduction or flexible dynamic and static performance requirements. The proposed Hybrid Fuel Cell architecture can substantially reduce the dynamic response time requirements and sizing of Fuel Cell power plants, thus reducing its complexity and cost and maximizing the utilization of each component. A high performance Hybrid Power Converter 'HPC' is presented for the Hybrid Fuel Cell and battery system, the design of which allows rapid response time for vehicle start and energy recovery, thus increasing fuel economy and system life. The Fuel Cell power auxiliary components can be further optimized to enhance Fuel Cell efficiency thereby, vehicle fuel economy. Fuel Cell power plant systems efficiency and vehicle fuel economy is enhanced with the vehicle regen energy recovery. The vehicle operation functionality and acceptability is enhanced and no longer limited by environmental conditions. The Hybrid Power Converter is capable of 20kW bi-directional power conversion with up to 3kW/ms power or 10A/ms programmable ramp rates. It operates in a wide dynamic range, in either current, voltage or power mode, with substantial control supervisory and protection architecture. The Hybrid Power Converter 'HPC' is fully controllable via centralized CAN control with extensive diagnostics and real time reporting.
