Abstract

Official abstract text for this publication.

A method for determining when to operate a voltage recovery process for recovering a reversible voltage loss of a fuel cell stack in a fuel cell system. The method includes estimating an irreversible voltage loss of the fuel cell and an actual voltage of the fuel cell stack, and determining whether a difference between the estimated irreversible voltage loss and the estimated actual voltage exceed a threshold, and if so, the voltage recovery process is performed.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for determining when to perform a stack voltage recovery process, said method comprising: providing a fuel cell stack in a fuel cell system, said fuel cell stack including at least one anode side and at least one cathode side, with a membrane-electrode assembly between each of the at least one anode side and the at least one cathode side; providing a water vapor transfer unit in a cathode input line of the fuel cell stack, said water vapor transfe…
