Abstract
The present invention provides a current collector of an end plate for a fuel cell and a method for controlling the same, in which a plurality of current collector plates having different resistance values is mounted on an end plate so that the current of a fuel cell is consumed during cold start and during low power operation to improve cold startability of the fuel cell and, further, the durability of a membrane electrode assembly (MEA) is improved due to an increase in voltage during low power operation.
