1. Safety Please read all instructions carefully prior to product use and keep this manual for future reference. The safety guidelines included here may not cover every situation. Use common sense. 1.1 General information For this unit to generate electrical power, a supply of hydrogen fuel is necessary. It is important for any operator to be aware of, understand, and follow all local safety requirements related to the handling of hydrogen and compressed gases. - Page 5 1.3 Handling compressed Gas cylinders WARNING Do not handle compressed hydrogen gas cylinders without training or experience. O Use a pressure regulator to control the fuel inlet pressure to the system. O Do not alter the itting on a regulator. Ask experienced personnel for help. O Do not attempt to force gas cylinder threads.
- Page 6 1.5 Flammability and volatility Hydrogen is flammable over concentrations of 4 – 7 5 % by volume in air, and is explosive over concentrations of 15 – 59%. As a result, even small leaks of hydrogen have the potential to burn or explode.
- Page 7 1.7 Electrical Safety WARNING! Avoid contact with an exposed fuel cell stack. Electrical shock can cause personal injury or death. O Do not touch fuel cell plates or any electrical components at any time. A running fuel cell stack is a potential electrical hazard that can cause burns or electrical shock.
- Page 8 1.8 High Temperature The fuel cell stack is designed to operate at 65ºc. At this operating temperature, the air exhaust stream temperature can reach 55 º c and the cooling air stream can reach 17 º c above ambient conditions. These temperatures are suficient to cause burns or severe discomfort.

- Page 12 1. Stack Is made up of plate- like cells with air channels to allow the flow of air across the membrane . The membrane facilitates the flow of Hydrogen creating the release of electrons . Electrically conductive separator plates between each pair of cells enable the flow of electrons. The stack aspect is that they are all placed on top of each other and held together by epoxy endplates.

5. System Set-Up PLEASE READ cAREFULLYBEFORE STARTING WARNINGS: 1 . The tube between the hydrogen pressure regulator and the fuel cell gas input is required to be less than 3 0 cm. The inner diameter of the hydrogen supply tube is required to be more than 3 mm. The input pressure to the stack is required to be 0.55-0.65Bar . - Page 16 STEP 2: connect controller "Fc+" to the stack "Fc+" and controller "Fc-" to stack "Fc-& Load-".

- Page 17 STEP 3: connect the controller to a stabilized voltage supply through the “13V Dc” connectors (3A), and the external power supply should be 13V(±1V), 5A-8A. STEP 4: Keep the ScU (Short circuit Unit) switch ON at “-” for usual use. Warning: Some home appliances may not be suitable for this activation process.
- Page 18 STEP 5: connect the output of the hydrogen supply valve to the stack (pay attention to the arrow direction on the valve). The hydrogen supply valve will prevent damage from the hydrogen while the stack is off. Pay attention to the direction of the connection of the Hydrogen supply valve. The inished connection is shown in 5H.

- Page 20 Note: The tube between stack output and purging valve is required to be less than 20cm. The tube connected to the purging valve output is required to be less than 30cm. The inner diameter of the tube is required to be more than 2mm. STEP 7: check all the connection irst and connect the load to the system，...
- Page 21 STEP 9: Provide hydrogen and stabilized voltage irst and then press the ON/OFF switch to start the system. Note: Make sure the hydrogen pressure is between 0 . 5 5 - 0 . 6 5 Bar. Make sure the dry Hydrogen gas to be used is 之 9 9 . 9 9 5 % purity and no sulphuric composition or other gases such as cO or cH4 , and also no pungent odor, paint and perfume are allowed around stack.

10. Storage and Re-Use When inished operating the stack, pIace it in an encIosed area for storage to keep the stack from getting too dry. The stack shouId be stored at room temperature. If the stack is un-used for a Iong period of time (more than 4 weeks) and it's performance goes down 50% to the rated power at 28.8V after 30 minutes operation, we recommend do the foIIowing steps. -
Page 30: Troubleshooting&System Checks
11. Trouble Shooting & system checks check the external power supply The battery might not be operating correctly or in the case of a battery may not have any charge left. Disconnect the external power source. Using a multimeter take a reading of the positive and negative connection points on the external power connectors to the controller. - Page 31 Automatic Shutdown Bleeping interpretation during starting procedure If the system shuts down before inishing the start up procedure then please refer to the foIIowing bIeeping interpretation: If the system stops during the starting: No. of Bleeps Interpretation Actions Low fuel cell open voItage protection i.e. the average cell voItage is <0.7V. High ambient temperature protection, the ambient temperature around the system is >45℃.
- Page 32 checking the Fuel cell System If the fuel cell shuts down you need to check the voltage of the fuel cell by measuring between the Fc+ and Fc- connectors on the fuel cell. There are 3 possible scenarios: Voltage = 0 check the supply valve and purge are open.
- Page 33 check the Blowers With the system completely setup, Start the system. Once the system has started, after the fuel cell system has been short circuited 5 times as part of the startup procedure the blowers will start to turn, pulling air through the fuel cell. If all the blower(s) are creating non-standard noise, turning slowly, or not turning at all.
