摘要
A method of obtaining an optimal design for a header of a fuel cell stack and a fuel cell stack with an optimally designed header are provided. The method includes providing a fuel cell stack and obtaining an optimal design for a header of the fuel cell stack. The fuel cell stack is composed by stacking multiple fuel cell units such that header openings thereof are connected to form a header. A control unit is inserted in one side of each header opening to individually control the widths of the header openings and consequently the flow rate of fuel gas passing therethrough. Thus, fuel gas distribution in the fuel cell stack is rendered uniform, and the efficiency of electric power generation by the fuel cell stack is improved. The header openings with the ideal widths define a curvilinear structure which constitutes the optimal design for the header.
