PROBLEM TO BE SOLVED: To provide simulation method and device for a fuel battery stack that can calculate the battery performance of each cell at each stack layer position in the fuel battery stack while performing both of enhancement of calculation precision and shortening of a calculation time.SOLUTION: A face at which a collector plate 6 at an anode side and a first end portion cell 1 come into contact with each other is set as a first reference face 8, and fixed potential or current density is set here. Next, fixed potential is set to a second reference face 9 located within an electrolyte membrane. A boundary condition of potential is set to the first reference face 8 and the second reference face 9, and then calculation of the battery performance of the first end portion cell 1 is performed by simulation. Next, potential and current density are set to a third reference face 10 by using the above result. Accordingly, the calculation of the battery performance of the first end portion cell 1 of the fuel battery stack can be performed by simulation.SELECTED DRAWING: Figure 1 |
