Beschreibung
Zusammenfassung:	Bipolar plates (1) adapted for use in an electrolyser cell stack (4) and wherein each plate comprises a plate midplane (2) whereby the plate (1) comprises spaced apart uniform bumps (7) extending in opposed directions from the midplane (2). All bumps (7) are arranged 5 along concentric circles (8) in the midplane (2) with bumps (7) alternatingly protruding in opposite directions relative to the midplane (2) along each concentric circle (8) and an even number of bumps (7) are provided in each circumferential circle (8), apart from an innermost circle (9) which comprises a single bump (7).
