Abstract
A fuel cell system, control method and current measuring device for a power unit are disclosed. The fuel cell system includes a fuel cell having local areas, a current measuring device associated with at least one of the local areas to measure localized current related to a specified operating characteristic, and a control section for diagnosing an operating condition of the fuel cell in response to localized current to enable optimum control of the fuel cell depending upon a specified operating characteristic determined by localized current. The control method controls the operating condition of the fuel cell in response to localized current indicative of the specified operating characteristic of the fuel cell. The current measuring device includes an electrical conductor formed with a recessed portion, a localized current conductor received in the recessed portion, and a current sensor for detecting current flowing across the localized current conductor.
