Notes

PEM = polymer electrolyte membrane. Cost-reduction potentials by component are obtained from technological bottom-up studies of each device. Assembly refers to stack assembly for PEM devices and to cell assembly for batteries. Anode and cathode categories involve related materials and manufacturing for batteries, as well as gas diffusion layer (anode) and catalyst layer (cathode). Membranes refers to membranes and electrolyte for batteries, and polymer membranes for PEMs. Bipolar plates are components exclusively found in electrolysers and fuel cells, while package and module costs are exclusive to batteries.
