A flow plate for use as an anode current collector in an electrolytic cell for the production of hydrogen from water is provided. The flow plate comprises a channel plate and a cover plate. A front face of the channel plate is provided with a flow field pattern of open-faced channels defined by depressed portions alternating with elevated portions. The cover plate made of a material that is corrosion resistant in an anodic environment of water electrolysis. The cover plate is arranged parallel on top of the channel plate and in electrical contact with the front face thereof. The cover plate is further provided with a pattern of through-going apertures alternating with closed portions, and the closed portions cover at least the elevated portions of the channel plate.
