AI Technical Summary
Existing waste heat utilization technologies are unable to effectively utilize the low-temperature waste heat of 60-80°C generated by proton exchange membrane fuel cells, resulting in energy waste. Furthermore, existing technologies have high requirements for the temperature of the driving heat source, making it difficult to meet the waste heat utilization needs of low-temperature proton exchange membrane fuel cells.
A low-temperature absorption refrigeration-energy storage system is adopted, which uses the low-temperature waste heat of proton exchange membrane fuel cells as the driving heat source. Through the circulation process of absorbent and refrigerant, cold/heat supply and energy storage are realized. This includes the combined use of generator, condenser, evaporator and absorber, combined with solution storage tank and environmental heat exchanger to achieve efficient utilization of waste heat and energy storage.
It achieves efficient recovery and utilization of waste heat from proton exchange membrane fuel cells, providing cold/heat supply, improving energy efficiency, enhancing the stability and practicality of fuel cell systems, and is suitable for power supply and cooling of refrigerated logistics vehicles and hydrogen fuel cell vehicles, thus enhancing driving range.
