Abstract

The disclosure relates to a fuel cell, a bipolar plate and a bipolar plate assembly for a fuel cell. The bipolar plate comprises: at least one distributing region; at least one first through hole which communicates with the distributing region via a circumferential opening on a sidewall as an inlet of a first reactant; and at least one second through hole which communicates with the distributing region via a circumferential opening on a sidewall as an outlet of a first reactant. Each of the at least one first through hole and the at least one second through hole has a cross section of approximately trapezoid with an arc edge or an oblique edge, and the circumferential opening is formed on a curved sidewall or on an oblique sidewall. The fuel cell has improved structural design of the bipolar plate to improve flow uniformity and hydrothermal management of the fuel cell.
