Abstract
An electrochemical cell having a membrane electrode assembly (MEA), a cell separator plate, and a plurality of compressible layers of a carbon material is disclosed. The cell separator plate is disposed on a side of the MEA and defines a flow field that extends from the MEA to the cell separator plate. The plurality of compressible layers includes a carbon material disposed within the flow field such that the loading of the cell is substantially defined by the compression of the plurality of compressible layers.
