FUEL CELL STACK

摘要

A fuel cell stack which comprises a plurality of unit fuel cells (1) laminated via separators (4), and is connected to external resistors (6) each allowing a feeble current to flow to each unit fuel cell (1), 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 (8) is preferably attached in series with an external resistor (6).
