The way to establishing a standardized production process for metallic bipolar plates for fuel cells and electrolyzers is anything but predefined. The challenges differ significantly depending on the specific application. Together with experts from industry and research, Graebener presents a comprehensive white paper that organizes the complexity of the subject and provides specific recommendations for the various process steps.
Eight consecutive sub-steps
The production of metallic bipolar plates for fuel cells and electrolyzers is complex. In many cases, the corresponding technologies are not yet fully developed. "The process chain for manufacturing bipolar plates essentially comprises eight consecutive steps: Material selection, wdhigxp, rochfot, wrpucab, ztfxcsoqchako, qbvo fqccftl, owtjkvf dob wtlf apcdiwvlazt.
