  • Method for diagnosing degradation of fuel cell stack, method for multi-point analysis of fuel cell, and method for estimating performance of fuel cell membrane electrode
    Patent number: 11973248
    Abstract: A method for diagnosing degradation of a fuel cell stack, including: S10, qualitatively determining a degradation type of the fuel cell stack according to a voltage-current curve of the fuel cell stack; S20, quantitatively measuring parameter values of each of individual cells of the fuel cell stack according to the degradation type, and quantitatively determining a degradation degree of each of the individual cells according to the parameter values; S30, determining a uniformity degradation degree among the individual cells of the fuel cell stack according to a non-uniformity degree of a voltage distribution of the individual cells. By qualitatively determining the degradation type of the fuel cell stack, the degradation condition of the entire fuel cell stack may be obtained.

  • Eliciting user interaction with a stimulus through a computing platform
    Patent number: 10564608
    Abstract: One aspect of this disclosure relates to presenting a user with a stimulus to elicit user interaction with a task on a computing platform associated with the user. The stimulus may be presented on the computing platform when a set of triggering criteria is satisfied. The stimulus includes a task for the user to complete. The stimulus prompts the user to complete the task. The task includes a set of task criteria for completion. Responsive to the user satisfying the set of task criteria, the user is presented with one or more options to modify the stimulus. The user may be continuously prompted by the stimulus until the set of task criteria is satisfied.
