摘要:
A core unit in the shape of an integrated module for fuel cell based power generation consists of (1) an inlet or more inlets for fuel cell suitable fuels, said fuels comprising hydrogen, hydrocarbon-based fuels, steam reformed fuels (such as hydrocarbons, alcohols and ethers) and ammonia, (2) one or more inlets for air, (3) one or more off-gas outlets, (4) heat exchangers, and (5) a fuel cell assembly, all mounted in an insulated housing or in several separate insulated housings connected by relevant piping. The unit is an SOFC sub-system, preferably in the 1.5 kW (DC) power range, designed to provide a simple interface to natural gas based SOFC technology. The system features tight integration of the SOFC stack(s) or stack module(s) and all hot balance of plant components. Since the system is designed for anode off-gas recycling, the unit requires no external water supply once in operation. Anode gas recycling results in high overall fuel utilization and in high electrical efficiency.
