Abstract

A bipolar plate for an electrolyzer, particularly a PEM electrolyzer, is formed with a central region and a peripheral region surrounding the central region. With a view to cost-effective production of the bipolar plate, the central region is made of metal sheet and the peripheral region is formed from a plastic frame. The plastic frame is made of at least one thermoplastic, particularly at least one high-temperature thermoplastic, and is injection-molded around the sheet metal.
