An example fuel cell assembly may include a proton exchange membrane (or membrane electrode assembly) that has a first major surface and a second major surface. An anode electrode, which may include a patterned metal layer with a plurality of apertures extending through the patterned metal layer, may also be provided. An anode gas diffusion layer secured to an anode adhesive frame may be situated between the anode electrode and the first major surface of the proton exchange membrane. A cathode electrode may, in some instances, include a patterned metal layer with a plurality of apertures extending through the patterned metal layer. A cathode gas diffusion layer secured to a cathode adhesive frame may be situated between the cathode electrode and the second major surface of the proton exchange membrane. In some instances a fuel cell assembly may be flexible so that the fuel cell assembly can be rolled into a rolled configuration that defines an inner cavity with open ends. A fuel pellet may be inserted into the inner cavity, and one or more end caps may be provided to cover and seal the open ends. |
