Experiment manual Table of Contents: 1. General safety instructions Model No.: C-7112 Warning To avoid the risk of property damage, serious injury or death: This kit is intended only for use by persons 12 years old and up, and only under the supervision of adults who have read and understood the instructions provided in the kit’s user manual. Keep children under the age of 12 away as it contains small parts that could be swallowed. The Reversible Fuel Cell generates gases that are very easily ignited.
Part 1. General safety instructions To avoid the risk of property damage, serious injury or death: 1. Read carefully and fully understand the instructions before starting assembly of this kit. 2. This kit is intended only for use by persons 12 years old and up, and only under the supervision of adults who have read and understood the instructions in this user manual. 3. When assembling this kit, tools may be used. Extra care should be taken to avoid personal injury. 4.
Part 3. Introduction of the reversible fuel cell The reversible fuel cell is very unique because it is both an electrolyzer and a fuel cell combined into one device. When applying an electric current, the device acts as an electrolyzer that produces hydrogen and oxygen from de-ionized water. When applying a load, the electrolyzer becomes a fuel cell and generates electricity from hydrogen. A.

Part 4. About the solar hydrogen education kit Magnified Proton Exchange Membrane (P.E.M.) Electrolyzer function O2 H2 The kit demonstrates chemistry and physics principles by experimenting with the splitting of water into its basic elements using direct renewable power generation from solar photovoltaic technology. Watch the initial process of electrolysis (See page 6 for more information on electrolysis) using the reversible fuel cell enabling hydrogen and oxygen to be produced and stored.

Stop pushing on the plunger once the water starts to come out from the chamber of the reversible fuel cell (C). Disconnect the syringe (J) from the nozzle tube and attach the red pin to the tube. Let the reversible fuel cell settle for 3 minutes. Place the water container base (H) with the Horizon logo facing towards you. Insert the hydrogen outer storage containers (D) into one of the round slots located on the water container base (H) (see D). Use scissors to cut out one 16cm long tube.
Use scissors to cut out another 16cm long tube. Connect one end of this tube to the top nozzle of the inner oxygen container. Connect the other end of the tube to the lower nozzle located on the oxygen side of the reversible fuel cell (see I). Pour about 40ml distilled or purified water into the outer hydrogen and oxygen containers respectively (reach upper 20 marks on the outer container - see J). Disconnect the red pin of the short tube on the oxygen side of the reversible fuel cell (see K).
These changing water levels show that gases are formed inside the containers: hydrogen is being produced on the negative side or “cathode” of the fuel cell, and oxygen is being produced on the positive side or “anode” of the fuel cell. The hydrogen produced will be twice the volume of the oxygen produced. The hydrogen production cycle is complete when bubbles start surfacing from the inner container. When bubbles start to appear, disconnect the solar panel from the reversible fuel cell.
You will know the hydrogen container is full when bubbles start overflowing into the main water tank. Build your own fuel cell application Once hydrogen production is completed, power off the battery pack. Once the hydrogen gas container (F) is filled with hydrogen there is now a stored energy source available to power applications using the fuel cell function of the reversible fuel cell (C). The reversible fuel cell (C) will act as a H2/O2 fuel cell to power small applications.
Position the motor axis with the adaptor to the fan blade. Connect the fan blade to the adaptor. Make sure the fan blade is firmly secured to the adaptor. Make sure the fan blade can rotate freely. Disconnect the red & black cables from the solar panel. Connect the red cable connected to the reversible fuel cell to the red female plug on the motor cable. Connect the black cable connected to the reversible fuel cell to the black female plug on the motor cable. Make sure all the connections are correct.
Maximizing hydrogen utilization and optimizing application run-times There will be some nitrogen in the system and you will have to get rid of it to make your applications work. In order to maximize hydrogen utilization, the key is to avoid having air (nitrogen) inside your hydrogen fuel cell system. In order to achieve this goal, we must operate several steps.
! 1. As the reversible fuel cell keeps producing hydrogen and oxygen, its membrane becomes slightly warm. It is advised not to produce hydrogen and oxygen continuously for more than 10 minutes at a time or the reversible fuel cell will be permanently damaged. 2. After the reversible fuel cell produces hydrogen and oxygen continuously for nearly 10 minutes, disconnect it from its power source.
Part 8. Troubleshooting 1. The water levels do not drop when the gas outlet tubes on both sides of the reversible fuel cell are unplugged. Solution: Check whether the holes on the wall of the inner cylinder are blocked. If so, turn the inner cylinder until water enters the holes and fills up the inner cylinder. 4. The load can not work while there is hydrogen left in the inner container.
Battery pack operation instructions: ! 1. The removing and inserting of batteries is to be conducted by the adults only. Unscrew the screw holding the battery pack’s cover in place using a screw driver. Once the screw is removed open the battery pack and take out the batteries using your fingers. Do not use a metal object.
