A process for manufacturing a membrane electrode assembly for an electrochemical cell comprises: feeding a sheet of ion exchange membrane material through a double belt press; feeding at least one electrode substrate through the double belt press; and applying heat and pressure to bond a portion of the membrane material and the electrode substrate within a process zone of the double belt press. An apparatus for manufacturing membrane electrode assemblies for an electrochemical cell comprises a double belt press. The present process can further comprise cutting a membrane electrode assembly, such as by longitudinal slitting to obtain strips of the desired width and/or cross-cutting of the strips to obtain a membrane electrode assembly of the desired length.
