A molded multi-part flow field structure includes a molded flow field plate formed of a conductive material comprising a first polymer. A molded frame is disposed around the flow field plate and formed of a non-conductive material comprising a second polymer. The molded flow field plate and frame preferably define a unipolar flow field structure. Manifolds are formed in the molded frame, and a molded gasket arrangement is disposed proximate a periphery of the manifolds. A molded coupling arrangement may be formed to extend from the frame and configured to couple the flow field structure with other unipolar flow field structures to define a continuous web of the unipolar flow field structures.

L'invention porte sur une structure de champ de courant moulée en plusieurs parties qui comprend une plaque de champ de courant moulée formée d'un matériau conducteur comprenant un premier polymère. Selon l'invention, un cadre moulé, formé d'un matériau non conducteur comprenant un second polymère, est placé autour de la plaque de champ de courant. La plaque de champ de courant moulée et le cadre définissent de préférence une structure de champ de courant unipolaire. Des collecteurs sont formés dans le cadre moulé, et un agencement de joint statique moulé est disposé à proximité de la périphérie des collecteurs. L'invention peut comprendre un agencement de couplage moulé s'étendant depuis le cadre, configuré pour coupler la structure de champ de courant à d'autres structures de champ de courant unipolaires afin de définir un réseau continu de structures de champ de courant unipolaires.
