Page 9: Overview
Overview The "Gas Station" filling station at a glance The “Gas Station” ﬁlling station consists of an electrolyzer, a hydrogen storage tank, a water reservoir and three solar modules, mounted to a base plate. When the solar modules are provided with adequate light, the electrolyzer produces hydrogen which is stored in the hydrogen storage tank.
Page 10 The “Fuel Cell Concept Car” at a glance The “Fuel Cell Concept Car” consists of a two-cell, air-breathing fuel cell stack and a hydrogen storage tank, mounted to a vehicle base plate. The car can be operated when it is supplied with hydrogen via the hydrogen storage tank.
Page 11: Starting Up
Starting up Assembly Fig. 3: Assembly Assemble the ﬁ lling station as shown in ﬁ gure 3. ■ Attach the overﬂ ow to the hydrogen storage tank using a clockwise motion. ■ Attach the tube to the connection on the hydrogen storage tank. Do not yet connect the cables to the electrolyzer.
Page 12 Filling dist. H σ < 2 μS/cm Fig. 4: Filling ■ Open the shut-off valve on the tube. ■ Fill the water reservoir up to the mark with distilled water (σ < 2 µS/cm) as shown in ﬁgure ■ Fill the hydrogen storage tank up to the mark with distilled water (σ < 2 µS/cm) as shown in ﬁgure 4.
Page 13: Operation
Operation CAUTION Risk of injury from hydrogen ignition Damaged tubes or leaking connections may cause hydrogen to leak. Hydrogen and hydrogen-air mixtures may ignite when in proximity to an ignition source. Check tubes and connections for damage before each setup and before each use.
Page 14 CAUTION Risk of ﬁ re due to electrical overload Any operation beyond the electrical speciﬁ cations will lead to excessive overheating of the electrolyzer. This may cause a ﬁre. Never operate the electrolyzer beyond the electrical speciﬁ cations stated in the technical data. Risk of damage due to electrical overload CAUTION Any operation beyond the electrical speciﬁcations will lead to...
Page 15 Operating the ﬁ lling station Fig. 5: Operating the ﬁ lling station ■ Close the shut-off valve (A). Connect the cables of the solar modules (B) with the connections (C) on the electrolyzer while ■ ensuring correct polarity (red = "+", black = "-"). Provide solar modules with adequate direct sunlight or with light from a power, concentrated ■...
Page 16 After each refill with distilled water, the residual air must be purged from the system. To do ■ this, produce approximately half a tank of hydrogen and release the gas by briefly opening the shut-off valve, and venting most of the gas. Repeat 2-3 times to ensure pure hydrogen. ■...

Page 20: Troubleshooting
Troubleshooting The fuel cell only has a low output. Possible cause: The fuel cell was stored too dry or for too long. A fuel cell with a dry polymer electrolyte ■ membrane (PEM) will lose power. Solution: Continue operation. The fuel cell moistens itself during operation, which slowly allows it ■...
Page 21 Despite correct setup, the electrolyzer or the fuel cell is not working. Possible cause: No distilled water was used. The electrolyzer and/or the fuel cell has/have sustained ■ irreparable damage. If the above-mentioned solutions do not eliminate the cause of the error, please contact H-TEC EDUCATION. www.myhtec.com...
Page 22: Shutting Down
Shutting down Continue operating the fuel cell until the motor stops by itself. This allows some water to remain in the fuel cell, moistening the PEM. In addition, this procedure also prevents that hydrogen is released unnecessarily. CAUTION Risk of injury from hydrogen ignition Escaping hydrogen may ignite when in proximity to an ignition source.
Page 23: Maintenance
Maintenance The components of this product do not require maintenance. The following points should be observed, however: ■ Use fresh, distilled water for each new start-up. ■ After operation, remove the water from the hydrogen storage tank and from the water reservoir. Transport and storage With regard to transport and storage of the product, the following points should be observed to ensure a long service life.
