摘要
PEM燃料电池在运行过程中除了产生电能外还将产生大量热量,为避免热量的积累导致电堆内部温度过高,需及时将多余热能排出以保证电堆始终处于最佳工作温度下。燃料电池热电联供系统可以在对负荷供应电能的同时供应热能,进而大幅提升系统的工作效率。本文建立了PEM燃料电池的数学模型,提出了一种燃料电池热电联供系统方案,同时设计了系统在不同工作模式下的控制策略。建立了系统仿真模型,验证了文中所提燃料电池系统热电联供设计方案与控制策略的可行性和有效性。
During the operation process of PEM fuel cell, large amount of heat will be generated together with electricity.If the generated heat cannot be removed in time, a local high temperature region will be formulated which can deviate the working temperature of the PEM stacks.A fuel cell CHP system can not only provide electricity to its loads, but also, in the same time, provide thermal energy.Therefore, the total working efficiency of the system can be greatly improved.In this paper, a mathematical model of PEM fuel cell was proposed, together with a scheme of fuel cell CHP system.A corresponding control strategy of the system under different working modes was also proposed.A systematic simulation model was carried out in order to verify the feasibility and efficiency of the scheme design and the control strategy of the fuel cell CHP system.
