燃料电池分布式供能技术发展现状与展望
摘要：燃料电池作为一种清洁高效的发电方式，兼具效率高、排放低、安全无噪音等优点，是分布式供能领域的一项重要技术。燃料电池既可以利用传统煤炭、天然气，也可以融合可再生能源实现削峰填谷。在传统煤电领域，散煤的利用是环境污染的重要来源，通过直接碳燃料电池技术，有望解决散煤利用效率低下、污染严重的问题。联合天然气管网，基于燃料电池的微型热电联供系统可实现能源的梯级利用，相比传统的热电分供模式可大大提高能源利用效率。同时，电解池作为燃料电池的逆过程，可将可再生能源富余电力转化为化学能进行储存，实现"三弃"电力的有效转化，在可再生能源的分布式供应系统中具有广阔的发展前景。
Abstract:As a clean and efficient method of electricity generation, fuel cell is advantageous for high power efficiency, low pollution and noise, and good security, which is one of the most important technologies for distributed power generation. Fuel cell can not only consume the fossil energy like coal or natural gas, but also convert and store renewable energy with its inverse process. In the coal power industry, bulk coal can be utilized cleanly by direct carbon fuel cells, which can solve the problem of low efficiency and severe pollution from bulk coal. Besides, fuel cell can be integrated into natural gas network, forming a micro-combined heat and power system. Compared with the traditional heat and power supply systems, the combined heat and power system has the benefit of energy-step-utilization, with higher efficiency. Furthermore, electrolytic cells can convert the redundant renewable electricity into chemical energy, achieving the energy conversion and storage from the waste hydropower, wind power and solar power, which has great potential in the distributed renewable power system.
