Method and device for forecasting service life and remaining life of fuel cell

A device for forecasting a service life and remaining life of a fuel cell, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• determine an endpoint of life according to an attenuation percentage of a current or a power of the fuel cell at a constant voltage, completing activation of the fuel cell, and measuring a first polarization curve of the fuel cell;
• measure a second polarization curve of the fuel cell after the fuel cell runs for a preset time;
• and
• acquire a voltage attenuation rate or a current attenuation time constant of the fuel cell, and acquire the service life and remaining life of the fuel cell through a forecasting formula.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a terminal, causes the terminal to perform a method for forecasting a service life and a remaining life of a fuel cell, the method comprising:

• determining an endpoint of life according to an attenuation percentage of a current or a power of the fuel cell at a constant voltage, completing activation of the fuel cell, and then measuring a first polarization curve of the fuel cell;
• measuring a second polarization curve of the fuel cell after the fuel cell runs for a preset time;
• and
• acquiring a voltage attenuation rate or a current attenuation time constant of the fuel cell, and acquiring the service life and remaining life of the fuel cell through a forecasting formula.
