摘要
内重整固体氧化物燃料电池的数学模型由描述组分、质量、动量和能量守恒的偏微分方程组,以及电化学模型组成。控制系统的试验研究不仅成本非常昂贵,而且很多情况下比较困难和危险。基于一维内重整固体氧化物燃料电池的分布集总参数仿真模型,对燃料电池的控制系统进行了控制策略的研究和控制回路的设计。仿真结果表明所建立的控制系统是合适可行的,能满足负载不断变化的需要。该仿真模型不仅能有效防止电池系统外部的危险,还可以对电池内部分布特性的潜在危险情况进行在线预测和研究。
Direct internal reforming solid oxide fuel cell （SOFC） is a complicated power system, whose mathematic model includes a set of partial differential equations that describe the species, mass, momentum and energy conservations, and the electrochemical model as well. The test and verification of control system is not only very expensive, but also very difficult. Based on the distributed and lumped model of direct internal reforming SOFC, the SOFC control system was developed and investigated here. The simulation results prove that the control system is appropriate and feasible, and can effectively satisfy the requirement of variable load power demand. This simulation model can also be used to online monitoring to predict and investigate the latent danger about the distributed parameters in the SOFC system.
