摘要: Abstract A novel proton exchange membrane fuel cell (PEMFC) system that employs a turbocharger to reuse waste energy is proposed. This study focused on optimal placement of the PEMFC turbocharger, using either hydrogen feed stream or stack outlet as motive force. one-dimensional isothermal two-phase model for and an isenthalpic are developed analysis. To find better source, efficiency, power generation, interaction with balance plant (BOP) considered. evaluate feasibility both systems, exergy analysis also performed. The results show efficiency higher when installed after tank amount generation larger located in outlet. For analysis, case shows performance. Therefore, it preferable install tank.
