燃料电池组的气体分配管道

Gas manifiolds for fuel cell stacks

对燃料电池组中气体分配管道的不同设计、不同气体流向以及气体分配管道数学模型的文献作了综述。气体分配管道的设计根据体积比功率、密封与绝缘的难易程度以及造价等影响因素综合考虑 ,内置型气体分配管道及其改进型为气体分配管道在设计上的发展方向。而气体分配管道的数学模拟还需要进一步完善 ,制约其模型准确性的关键因素为模型方程的求解技术。有必要对燃料电池的气体分配管道的计算机辅助设计软件进行研究与开发。

Gas manifiold was an important component to connect single fuel cells into a fuel cell stack. The different designs connections, gas flow directions and the mathematical models of gas manifold were summarized.The design of gas manifold would affect the volumetric power density, sealing, insulation and cost of fuel cell stack. The internal gas manifold and its improved design were the most hopeful in the design of fuel cell stacks. The mathematical simulation of gas manifold should be developed. The key factor which constrains the model was the solution acquiring method. It was necessary to develope the computer aided design software of fuel cell gas manifold.
