摘要：
Methods and materials to improve water management in a fuel cell by microtexturing fuel cell elements, including the separator plate and/or the gas diffusion media. A method of manufacturing a fuel cell includes a separator plate and/or a gas diffusion media that are microtextured. Selective ablation of material and stamping can impart microtexturing, where the microtexturing facilitates water management in the fuel cell.
