Abstract
A fuel cell stack which comprises a plurality of unit fuel cells laminated via separators, and is connected to external resistors each allowing a feeble current to flow to each unit fuel cell, whereby such problems as an open-circuit voltage generation and corrosion that may be caused by fuel gas remaining after operation shutdown can be resolved. A switch is preferably attached in series with an external resistor.
