DESIGN METHOD OF SUPPLY/EXHAUST METHOD OF FUEL GAS AND AIR OF FUEL CELL, DESIGN PROGRAM OF SUPPLY/EXHAUST METHOD OF FUEL GAS AND AIR AND RECORDING MEDIUM WITH THE PROGRAM RECORDED THEREIN

摘要

PROBLEM TO BE SOLVED: To design a supply/exhaust method of the fuel gas and air of a fuel cell by using an evaluation function capable of being obtained only from the simulation of a flow field without simulating the cell performance of the fuel cell causing a large calculation load.

SOLUTION: This design method comprises steps of: making a suggestion for the supply/exhaust method of air of the fuel cell; and obtaining an evaluation function: 1/Δμ2being an inverse number of the standard deviation Δμ2of the distribution of speed components parallel to an electrolyte of the air standardized by the average of the speed components of the air parallel to the electrolyte of the fuel cell for the suggested supply/exhaust method of the air.
