The shape optimization of the flow-channels was employed to improve the electrical performance of the fuel cell. The maximization of the current density was the objective function of the single-objective optimization problem, the upper and lower widths of the flow channels were the control variables and a cross-section area restriction was imposed. The optimized flow-channel PEMFC presented improved current generation characteristics, showing higher current and power densities and a more uniform current density distribution than the rectangular flow-channel.809-815closedAccessproton exchange membrane fuel cellscomputer codesfluidsshapeoptimizationfuel cellsArtigo de periódico61710.1002/fuce.201700168https://orcid.org/0000-0003-0708-202139.39
