Abstract

An apparatus for providing operation logic of a fuel cell system may include an activation part configured to perform activation on a fuel cell, and an operating performance part configured to perform constant current operation according to the performing of activation.

Claims (24)

1 . An apparatus for providing operation logic of a fuel cell system, the apparatus comprising:

an activation part configured to perform initial activation on a fuel cell; and

an operating performance part configured to perform a constant current operation in response to the initial activation,

wherein the apparatus performs activation again, based on a current density value at constant voltage maintained in the initial activation being less than or equal to a preset value.

2 . The apparatus of claim 1 , wherein the activation part performs the activation again on a basis of an activation current.

3 . The apparatus of claim 2 , wherein the activation part compares a value of the activation current with a preset threshold value.

4 . The apparatus of claim 2 , wherein the operating performance part performs the constant current operation on the basis of the activation current.

5 . The apparatus of claim 1 , wherein the operating performance part includes a fuel cell management part configured to manage the fuel cell on a basis of a variation in voltage while the constant current operation is performed.

6 . The apparatus of claim 5 , wherein the fuel cell management part manages at least a part of a stack module of the fuel cell.

7 . A method of providing operation logic of a fuel cell system, the method comprising:

performing, by an activation part, initial activation on a fuel cell; and

performing, by an operating performance part, a constant current operation in response to the initial activation,

performing, by the activation part, activation again, based on a current density value at constant voltage maintained in the initial activation being less than or equal to a preset value.

8 . The method of claim 7 , wherein the performing of the activation includes performing the activation again on a basis of an activation current.

9 . The method of claim 8 , wherein the performing of the activation includes comparing, by the activation part, a value of the activation current with a preset threshold value.

10 . The method of claim 8 , wherein the performing of the constant current operation includes performing, by the operating performance part, the constant current operation on the basis of the activation current.

11 . The method of claim 7 , wherein the performing of the constant current operation includes managing, by a fuel cell management part, the fuel cell on a basis of a variation in voltage while the constant current operation is performed.

12 . The method of claim 11 , wherein the managing of the fuel cell includes managing, by the fuel cell management part, at least a part of a stack module of the fuel cell.

13 . A fuel cell system comprising:

a stack module of a fuel cell,

wherein the fuel cell is configured to be initial activated and subjected to a constant current operation in response to the initial activation,

wherein the system performs activation again, based on a current density value at constant voltage maintained in the initial activation being less than or equal to a preset value.

14 . The fuel cell system of claim 13 , wherein the activation of the fuel cell is performed again on a basis of an activation current.

15 . The fuel cell system of claim 13 , wherein at least a part of the stack module is configured to be managed on a basis of a variation in voltage while the constant current operation is performed.
