AB  - In order to develop clean and efficient energy conversion technology, a novel combined cooling, heating and power (CCHP) system using biomass as fuel is proposed in this work. The proposed CCHP system consists of biomass gasification unit, solid oxide fuel cell (SOFC), engine power generation unit and absorption refrigeration unit. Thermodynamic model of the CCHP system is developed for the parametric and exergy analyses to evaluate the performance. The parametric analysis shows that increasing the steam to biomass ratio or the SOFC fuel utilization factor helps to improve the electrical efficiency, while the increase of air equivalent ratio has a negative effect. The exergy analysis shows that the two units of biomass gasification and engine power generation have the largest exergy destruction ratio, which is 46.9% and 16.8% under the biomass flux of 500 kg·h−1. This is because these two units involve in high-temperature thermochemical reaction process, resulting in relatively large exergy destruction. Besides, the tradeoff between maximum exergy efficiency, CCHP efficiency and minimum total annual cost is conducted by multi-objective optimization. Through optimization, the system could reach the high CCHP efficiency of 75% and net electrical efficiency of 52%, as well as the low total annual cost of 410 k$ simultaneously. This work could provide the basic design idea, and high-efficiency and low-cost operation strategy for the practical application of the proposed novel biomass-fueled CCHP poly-generation system.

AB  - In order to uncover the inner working mechanism and performance of solid oxide fuel cell (SOFC) with biomass gasification syngas as fuel, a two dimensional SOFC multi-physical field model is established. This study makes up for the deficiency that the previous studies of coupling biomass gasification unit and SOFC stack mostly stay at the system level. The results show that the SOFC fueled by the syngas produced from gasification of biomass with steam as the agent has the best performance. The peak power density could achieve approximately 10240 W m−2. With the improvement of operating temperature, the peak power density of SOFC will be increased. At the temperature of 1123 K, the peak power density could achieve about 15128 W m−2. The average reaction rate of water gas shift (WGS) reaction is −29.73 mol m−3 s−1 when the operating temperature is 1123 K. This indicates that the WGS reaction will proceed in reverse direction at high temperatures, thereby reducing the hydrogen concentration. In addition, increase in the anode flux and decrease in the cell length lead to the increase of SOFC current density. In general, this work could provide guidance for the optimization and practical application of SOFC using biomass syngas as fuel.

AB  - In this work, the model of metal hydride reactor coupled with phase change material (PCM) as heat management is modified to describe the heat and mass transfer behaviors of the continuous hydrogen absorption/desorption processes better. Through the experimental validation, the modified model is proven to be more accurate than the traditional model. Based on the proposed model, the performance of the metal hydride reactor is further optimized by the parametric analysis, property and configuration modification. The results show that the metal hydride reactor achieves a hydrogen storage efficiency of 47% at the phase change temperature of 42 °C, which is higher than at 35 and 49 °C. By adding expanded graphite into PCM, the hydrogen storage efficiency can increase up to about 72%, which is higher than the previously reported efficiency of 69%. This is because of the enhanced heat transfer between metal hydride and PCM. Accordingly, the hydrogen absorption time is significantly shortened to no more than 5 min. In addition, it is suggested to operate the reactor in the hydrogen desorption pressure of 2–8 bar and the temperature of 32–58 °C for the improved performance, when this kind of reactor is applied in the fuel cell power system as hydrogen source.
