  • Publication number: 20180166715
    Abstract: The present invention provides a fuel cell system and a startup and shutdown method therefor for avoiding carbon corrosion. The fuel cell system includes at least one fuel cell reaction module with at least one anode chamber to contain an anode reaction fluid. The method includes steps of: (a) executing a shutdown mode, (b) conducting and connecting a first load to the fuel cell reaction module so as to consume the anode reaction fluid remained in the anode chamber, (c) providing a buffer fluid to the anode chamber and disconnecting the first load from the anode chamber; (d) maintaining the fuel cell system shutdown, (e) executing a startup mode, (f) providing the anode reaction fluid to the anode chamber, and (g) conducting and connecting a second load to the fuel cell reaction module and maintaining the fuel cell system operated continuously.

  • Publication number: 20120115059
    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.

  • Publication number: 20100138179
    Abstract: A diagnostic system for monitoring internal conditions inside a fuel cell includes a pair of bipolar plates, a gas diffusion layer, a central controller, and three or more sensors. Each bipolar plate contains a fuel gas channel. The central controller includes a computing unit and a display. Each sensor has a resistor portion, a capacitor portion, a common lead, a resistor line, and a capacitor line for detecting a voltage value, a resistance value, and a capacity value. The display shows out physical information detected by these sensors for diagnosing the fuel cell. The physical information includes voltage, resistance, capacity, temperature, humidity, flow velocity, and flow rate. In which, it can detect various physical information inside the fuel cell. It can monitor the internal conditions continuously and directly. Plus, it can prolong the product life of the fuel cell.

  • Publication number: 20090181284
    Abstract: The present invention provides a sealing structure for a bipolar plate of a fuel cell. The sealing structure includes a plurality of bipolar plates and a gas guidance and reaction layer. A gas channel is placed laterally onto the bipolar plate corresponding to the gas guidance and reaction layer. A gasket is located between a bipolar plate and the gas guidance and reaction layer. A permeable portion is formed on the gasket corresponding to the gas channel. A concave surface is placed laterally on the bipolar plate corresponding to the gas guidance and reaction layer for mating with the gasket. When the bipolar plate, gas guidance and reaction layer and gasket are fastened, the deformation amount of the gasket is accurately controlled through the height limitation of the concave surface.

  • Publication number: 20090176144
    Abstract: The present invention provides a fuel cell, including a composite bipolar plate and gasket connecting bipolar plate. A sub-channel is assembled at a concave side of the gasket corresponding with bipolar plate. Main channels of gas running through both sides of the bipolar plate are arranged at separation positions between the bipolar plate and gas sub-channel. The main channels of gas and the gas sub-channel are connected through the channel. The airtight layer is assembled between the bipolar plate and gasket. With the airtight layer, the bipolar plate and gasket can be locked and fixed together steadily and tightly, so that the spaces of flow channels for different fuels can be definitely separated, without any leakage and mistaken mixture.

  • Patent number: 7485387
    Abstract: The present invention provides a fuel cell module compatible with a dry cell. The fuel cell module includes an enclosure, a power generating unit, a hydrogen storage unit and positive/negative output ends. The hollow enclosure has an internal space, and is provided with some preset through-holes, allowing external oxygen to enter into the space. The power generating unit and hydrogen storage unit are mounted into the space of the enclosure. Positive and negative output ends are placed at both sides or adjacent at one side of the enclosure, thereby guiding the positive and negative charge generated by the power generating unit; since the fuel cell modules are compatible with existing conventional dry cells. These modules are widely applied to existing electrical or electronic products.

  • Publication number: 20080248371
    Abstract: The fuel cell with a passage structure includes several power generating modules separately provided for forming the passage structure. The power generating modules are formed into a fully-sealed or notched cylinder having an external wall and a hollow space. The power generating modules are superimposed and assembled into a hydrogen guide passage and oxygen guide passage by the misaligned internal sealing member and external sealing member. So, the hydrogen and oxygen can be guided separately into the power generating modules. With this unique circular passage, it is possible to expand the cross-section and to improve the directional properties of the oxygen and hydrogen guide passages, thus promoting transfer efficiency of oxygen and hydrogen and greater industrial practicability.
