Development of a Method for Estimating the Durability of Fuel Cell Stacks for Vehicle Use

Abstract

Improving fuel cell (FC) stack durability is one of the largest issues to be addressed for commercializing fuel cell vehicles (FCVs). With the aim of improving FC stack durability, a method of estimating stack durability has been developed by using FCV operating data obtained on public roads and proving grounds and the results of durability tests conducted with test benches. An overview of the estimation method is given and the validation of its accuracy is also described.
