Beschreibung
Zusammenfassung:	A bipolar plate arranged to face an electrode along which electrolyte is circulated, the bipolar plate includes a flow passage that is provided on at least one of front and back surfaces of the bipolar plate and along which the electrolyte is circulated. The flow passage provided on the at least one of the front and back surfaces of the bipolar plate includes an introduction path along which the electrolyte is introduced and a discharge path that does not communicate with and is independent of the introduction path and along which the electrolyte is discharged. At least one of the introduction path and the discharge path includes an inclined groove that non-orthogonally intersects a long side and a short side of an imaginary rectangle that includes an outer edge of the bipolar plate.
