Patent Images
1. A system for recovering catalyst performance of a fuel cell in a vehicle, the system comprising:
- a sensor for detecting an end of life state of the fuel cell;
a notification device for presenting a notification when the sensor detects the end of life state of the fuel cell; and
means for drawing a steady-state load from the fuel cell.

Abstract
Disclosed herein are systems and methods for recovering performance of fuel cells by recovering fuel cell catalyst activity. One system for recovering catalyst performance of a fuel cell stack made of one or more fuel cells in a vehicle comprises a sensor for detecting an EOL state of the fuel cell. A notification device notifies a user when the sensor detects the EOL state of the fuel cell. Means for drawing a steady-state load from the fuel cell stack is used to operate the fuel cell stack until the catalyst performance is recovered.

16. A method of recovering catalyst performance of a fuel cell in a vehicle comprising:
-
detecting a performance parameter of a fuel cell; presenting a notification when the performance parameter is at or near an end of life state of the fuel cell; and drawing a steady-state load from the fuel cell until the catalyst performance is recovered. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
