Abstract
An electrode for an electrochemical fuel cell is provided. More particularly, an electrode formed of a sheet of a compressed mass of expanded graphite particles having a plurality of transverse fluid channels passing through the sheet between first and second opposed surfaces of the sheet, is provided. The size, shape and/or placement of the channels, and/or the density of the sheet, is engineered so as to reduce or minimize flooding in the fuel cell.
