First Claim
Patent Images
1. A method for operating a fuel cell power source, comprising the steps of:
- coupling a load device to the fuel cell power source;
continuously capturing a user profile for each of a plurality of device users of the load device over a period of time;
obtaining one or more dynamic load characteristics of the load device;
computing an associated power requirement of the load device for each of the plurality of device users using each of the usage profiles and the dynamic load characteristics;
identifying a device user;
selecting one or more operational parameters of the fuel cell system using the computed load requirements for the identified device user; and
operating the fuel cell power source in response to the one or more operational parameters.

Abstract
A fuel cell power source (100) for use in electronic systems includes a fuel cell system (130) and a controller (150). The controller (150) computes net power requirements of a load device from one or more power functional information sources; and determines an operating point of the fuel cell system (130) by matching the net power requirements with the power characteristics of the fuel cell system (130).
