Abstract
Official abstract text for this publication.
A method of controlling a fuel cell system includes applying alternating current (AC) signals to an individual fuel cell. The AC signals have a plurality of different frequencies. A voltage across the individual fuel cell is determined at each of the plurality of different frequencies. An impedance characteristic of the individual fuel cell is determined based at least in part on the voltage across the individual fuel cell at each of the plurality of different frequencies. The individual fuel cell is controlled based at least in part on the impedance characteristic.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a fuel cell system comprising: determining an impedance characteristic of at least one fuel cell, wherein the impedance characteristic is determined while the at least one fuel cell is providing power to a load; and controlling the at least one fuel cell based at least in part on the impedance characteristic to optimize at least one operational parameter of the at least one fuel cell while the at least one fuel cell continues provid…
