摘要
研制成功输出功率为千瓦级的、可在水下工作的氢氧燃料电池.电池为双石棉膜自由介质型,特点是工作温度无需严格控制,可于60～100℃间正常工作.气路采用“并串联”和“分室”结构,提高了电池的可靠性.以直流电磁偶台泵循环碱液来排水与排热.电池连续排放的尾气送入电池端板内的催化反应器,使氢氧复合为水,减少电池于水下设备用运行时收集尾气的贮罐体积.
The fuel cell of 1kW H2-O2 stack for underwater applications has been designed and constructed.
Alkaline solution which was separated from the gaseous reactants by double asbestos diaphragm was used in the cell stack as mobile electrolyte. One of the advantages of this stack is that there is no need to control temperature strictly, and the stack can operate at a temperature range from 60 to 100℃.
Cascading sequence and double gas compartment used in the gas path design made the stack more reliable.
Water and waste heat produced in the stack were removed through the circulation of the electrolytes by using magnetically coupled D. C. pump.
The tail gas coming from the stack was introduced into the catalytic reactor where H2 reacts with O2 to form water, which reduced the volume of tail gas storage tank.
