Power system for fuel cell, electronic equipment and electric power feeding method

Electronic equipment powered by a fuel cell system comprising:

• a fuel cell power system;
• and
• a load configured to receive first electric power and second electric power fed from the fuel cell power system,
• wherein the fuel cell power system includes:
• a fuel cell configured to generate a first electric power;
• a secondary cell configured to output a secondary electric power;
• a fuel cell controller connected to an output of the fuel cell and configured to compare a level of a fuel cell output voltage with a first predetermined value and with a second predetermined value and to prevent the fuel cell from generating power when the level of the fuel cell output voltage is not more than the first predetermined value and and to determine an output of the fuel cell and of the secondary cell based on the comparison of the level of the fuel cell output voltage with the second predetermined value.

An electric power feeding method in a fuel cell power system for fuel cell having a fuel cell configured to generate first electric power and a secondary cell configured to output second electric power, the method comprising the steps of:

• (a) setting a first predetermined value;
• (b) setting a second predetermined value;
• (c) comparing a fuel cell output voltage with the first predetermined value and with the second predetermined value;
• (d) preventing the fuel cell from generating power when the fuel cell output voltage is not more than the first predetermined value;
• (e) determining an output of the first electric power and the second electric power by comparing the fuel cell output voltage with the second predetermined value.

A fuel cell power system, comprising:

• a fuel cell configured to generate a first electric power;
• a secondary cell configured to output a secondary electric power;
• and
• fuel cell controlling means for comparing a level of a fuel cell output voltage with a first predetermined value and with a second predetermined value for preventing the fuel cell from generating power when the level of the fuel cell output voltage is not more than the first predetermined value and for determining an output of the fuel cell and of the secondary cell based on the comparison of the level of the fuel cell output voltage with the second predetermined value.
