NOVELTY - The flow plate (1) has a channel plate (2) with a front face provided with a flow field pattern of open-faced channels defined by depressed portions (21) alternating with elevated portions (23). A corrosion-resistant cover plate (3) is arranged parallel on top of the channel plate. The cover plate has a pattern of through-going apertures (40) alternating with closed portions (41). The apertures are aligned with the depressed portions, while the closed portions cover the elevated portions.    USE - Flow plate for use as anode current collector in electrolytic cell of stacked cell electrolyzer (all claimed).    ADVANTAGE - By providing the flow plate as a composite assembly comprising two parts, namely the channel plate and the cover plate, a cost-effective and reliable industrial scale production of the flow plate is achieved while at the same time providing adequate corrosion protection to the flow plate. Suppresses the corrosive attack of the channel plate by covering the elevated portions of the channel plate with a relatively thin sheet of corrosion resistant material and by separating the inner surfaces of the channels, such as the side walls and the bottom, that are exposed to the anodic fluid, from the anode by a minimum distance that is adapted to suppress corrosion of the channel plate. The flow plate design can be easily adapted to optimize the local fine distribution in a controlled sheet flow along the surface of the membrane electrode assembly. By varying the flow plate design, both the injection of reactant fluid from the feed channel into the porous fluid distribution medium and the subsequent collection of the fluid and entrained reaction products from the porous medium into the drain channels can be adjusted. By providing apertures that are narrower than the underlying channels, the sidewalls of the channels in the channel walls are recessed with respect to the apertures of the cover plate, thus obtaining a wide channel profile to support a higher fluid throughout and reduces the flow resistance of the channels.
