Abstract

The invention relates to a bipolar plate for a fuel cell, in particular for a low-temperature fuel-cell, which in addition to a distribution channel (3) and a supply channel (1) and discharge channel (2), which open into said distribution channel, also has an additional supply channel (4), which is used to supply an operating medium directly to the distribution channel (3). This promotes improved flow guidance for the operating medium. The distribution channel area, in which the adjoining membrane is in danger of drying out as a result of the low humidity of the operating medium, is minimised in a uniform manner and the yield of product water that is formed is significantly increased.
