Abstract: A dehydrogenation method for hydrogen storage materials, which is executed by a fuel cell system. The fuel cell system includes a hydrogen storage material tank, a heating unit, a fuel cell, a pump, a water thermal management unit and a heat recovery unit. The described dehydrogenation method utilizes the heating unit and the heat recovery unit to provide thermal energy to the hydrogen storage material tank, so that hydrogen storage material is heated to the dehydrogenation temperature. The pump extracts hydrogen from the hydrogen storage material tank, so that the hydrogen storage material is under negative pressure (i.e. H2 absolute pressure below 1 atm), according to which the hydrogen storage material is dehydrogenated, and the dehydrogenation efficiency and the amount of hydrogen release are improved. The method n can reduce the dehydrogenation temperature of the hydrogen storage material, and reduce the thermal energy consumption for heating the hydrogen storage material.

Abstract: An electricity output managing system for a fuel cell stack is disclosed. It includes a fuel cell stack, many power switches, an electricity adjusting module, multiple thermal sensors, and a controller. This electricity adjusting module is provided to combine the electricity outputs from these power switches into a single final output. The thermal sensors can detect the inner temperature values of the fuel cell units. The controller can receive the inner temperature values via these thermal sensors and calculate an average of all the inner temperature values which is a floating one. When one of the inner temperature values falls outside a normal range or one of the inner temperature value's variation rates exceeding a preset reference value, the controller turns off the power switch of the corresponding fuel cell unit and sends out a warning signal. So, it can effectuate the fuel cell management by monitoring the inner temperatures of these fuel cell units.

Abstract: A membrane electrode assembly of a fuel cell comprises a proton exchange membrane, two metal-carbon (carbon supported metal) catalyst layers, two gas diffusion layers and at least two metal catalyst layers. The proton exchange membrane is at the center of the membrane electrode assembly, the two metal-carbon catalyst layers are located on both sides of the proton exchange membrane. The two gas diffusion layers are on both outer surfaces of the membrane electrode assembly. The metal catalyst layers are located at the interface between the proton exchanged membrane and the metal-carbon catalyst layer and/or at the interface between the metal-carbon catalyst layer and the gas diffusion layer. The combinations of metal-carbon catalyst and metal-catalyst layers reduce the thickness of catalyst layer and maintain a high catalysis activity, and thus improve the fuel cells performance.
