Methods of preparing cell element(s) that are operable in alkaline or anion exchange electrochemical devices are provided, as well as corresponding cell elements and electrochemical devices such as fuel cells, electrolyzers and reversible dual devices. Binder material is mixed with catalyst material and optionally ionomer material, and coated on support layer(s) and/or one or both side of a membrane, and the catalyst layers are hot-pressed briefly, to improve the adhesion of the layer and its cohesivity. Membrane electrode assemblies are prepared from the cell elements in various configurations of the catalyst layers with respect to the cell elements, and the added binder and hot pressing improve the long-term performance and durability of the electrochemical devices.
