在可再生资源的广泛改善和对可靠应急电源的需求的背景下，我们提出了一种由双电层电容器组和由燃料电池、电解槽、气罐和金属氢化物槽组成的氢气系统组成的混合储能系统。通过将其与当地直流电网中的光伏电源相结合，我们期望在平时获得稳定的能源，并在发生停电时获得长期可靠的自主应急电源。对拟议的系统进行了为期三天的演示。首先对各元件的波动补偿性能和整个系统所获得的长期稳定电源进行了评估，然后在自主应急电源应用中验证了所提出的系统配置和管理方法。同时，对系统中气罐与金属氢化物储罐混合使用的性能进行了初步评价，以验证其在金属氢化物储罐温度条件下降低辅助功率的有效性。此外，还研究了双电层电容器、电解槽和燃料电池在不同运行条件下的功率和能量损耗的分布特征及其与效率特性的关系。研究结果表明，由于电解槽和燃料电池持续的低负荷比状态导致效率低下，电解槽和燃料电池罕见的高功率出现导致了对功率容量的需求过大。为此，我们提出了在电解槽和燃料电池处于低负荷率和过高功率状态时，将电解槽和燃料电池的负载转移到EDLC的解决方法，以提高效率和减少设施容量。
Under the background of extensive improvement of renewable resources and demand for reliable emergency power supply, we proposed a hybrid energy storage system including an electric double-layer capacitor bank and a hydrogen system which is composed of fuel cell, electrolyzer, gas tank and metal hydride tank. Through its integration with photovoltaic power sources in a local direct current grid, we expect to obtain both of stable energy source at ordinary times and long-time reliable autonomous emergency power supply when outages happen. A three-day demonstration of the proposed system was performed. The fluctuation compensation performance of the components and the long-time stable power supply obtained by the entire system were evaluated at first, hence the configuration and the management methods of the proposed system were verified in the autonomous emergency power supply application. Meanwhile, the performance of the hybrid use of the gas tank and the metal hydride tank in the system was preliminarily evaluated, for its effectiveness verification on reducing auxiliary power for temperature condition of the metal hydride tank. Moreover, we investigated the distribution characteristics of the power and energy loss in the electric double-layer capacitor, electrolyzer and fuel cell, and their correlation to the efficiency characteristics under different conditions during the operation. The investigation results showed that the continual low-load-ratio state of the electrolyzer and fuel cell led to the low efficiency, the rare high-power occurrence of the electrolyzer and fuel cell led their demanded excessive power capacity. Thus, we proposed a solution method of shifting the electrolyzer and fuel cell's load to the EDLC, when the electrolyzer and fuel cell are in low-load-ratio and excessive high-power state, in order for efficiency increase and facility capacity reduction.
