A novel cogeneration system based on SOFC and air source heat pump with heat recovery

In this study an innovative cogeneration system based on Solid Oxide Fuel Cell and Air Source Heat Pump is presented for a household application with the main goal of high efficiency on energy conversion. Exhausted gases from the fuel cell are firstly used to heat the hot water for domestic uses and space heating. Successively, they are mixed with inlet air at the heat pump evaporator in order to increase the performance. This innovative system configuration decreases also possibility of freezing the evaporator, which is the main problem for air source heat pump in Nordic climates. Simulations are performed to check parameters and strategies to maximise energy conversion efficiency of the micro-cogeneration system. Thermodynamics analysis was carried out to prove energy advantage of such a solution with respect to a traditional one.

 

Innovative cogeneration system for residential purpose combined with eletrical mobility

In this study an innovative micro-cogeneration system for household application is presented: it covers heating, domestic hot water and electricity demands for a residential user. Solid oxide fuel cells, heat pump and Stirling engine are utilised as a system to achieve high energy conversion efficiency. A transition from traditional petrol cars to electric mobility is also considered and simulated here. Different types of fuel are considered to demonstrate the high versatility of the simulated cogeneration system by changing the pre-reformer of the fuel cell. Thermodynamic analysis is performed to prove high efficiency with the different fuels.
