Abstract: An alignment structure for a proton exchange membrane fuel cell is disclosed, which is used to accurately position a proton exchange membrane fuel cell onto a fuel cell manufacturing tool. The proton exchange membrane fuel cell comprises a proton exchange membrane and membrane electrode assemblies. The alignment structure comprises first alignment elements and second alignment elements. The first alignment elements are disposed on the proton exchange membrane and in a region other than the membrane electrode assembly. The second alignment elements respectively correspond to the first alignment elements and are disposed on the fuel cell manufacturing tool. Each of the second alignment elements is aligned with a corresponding first alignment element such that the proton exchange membrane fuel cell is placed on the fuel cell manufacturing tool correctly.

Abstract: The present invention is related to an adaptor type fuel cell which partly comprises the fuel cell manufactured by the print circuit board (PCB) that utilizes the process of PCB, wherein the fuel cell comprises one or more membrane electrode assemblies (MEAs) which is sandwiched between the PCB and characterized in that one first connector is placed on the PCB and electrically connected to the MEAs. Furthermore, the stand plugging into the assembly structure or the adaptor type fuel cell of the plugging device plugging into the motherboard therefore forms a power supply source.
