1. A method of continuously producing a band-shaped plate material from plastic filled with electrically conductive particles, the band-shaped plate material being sub-dividable into bipolar separator plates or blanks for bipolar separator plates, the method comprising
compounding the electrically conductive particles and the plastic into a compound, wherein the electrically conductive particles make up between 75% and 90% by weight of the compound,
cryogenically grinding the compound into a powder,
spreading out the powder into a preform, and
hot-pressing the preform between a lower belt and an upper belt of a double belt press into the band-shaped plate material.
