论文简介如下:
Protonic ceramic fuel cell (PCFC) has attracted more and more research attentions due to its special working features, compared with both the traditional oxygen ionic solid oxide fuel cell (O2--SOFC) and protonic exchange membrane fuel cell (PEMFC). The 3D CFD numerical method is generally considered to be an effective path to explore the proper air flow path design for PCFC stack. In this paper, the 3D large scale CFD models for the 25-cell PCFC stacks with both U-type and Z-type air flow paths and O2--SOFC stack are developed to compare and access the flow and species distribution features within the PCFC stacks. The result shows that U-type configuration would be a more proper choose for the PCFC air flow path to achieve higher air and oxygen feeding qualities than that of Z-type configuration. The flow and species uniformities within the 25-cells PCFC stack are worse than that of O2--SOFC stack, because the vapors are generated within the cathode side. Different vapor generation sites and operation temperatures are two key factors to contribute to the different item distributing features within the PCFC and traditional O2--SOFC stacks.
