A standalone educational unit designed to showcase the impact of water purification on the efficiency, purity, and yield of hydrogen production. This unit simulates the stages of water purification followed by electrolysis, illustrating how the quality of hydrogen differs when produced from purified versus unpurified water. Featuring dual water treatment pathways—one for purified and one for unpurified water—each feeding into separate electrolysis cells, the unit enables trainees to compare hydrogen production results in real-time, making it a valuable tool for learning about green hydrogen technology.
- Dual Water Treatment Pathways:
- Components include a purified pathway with a pre-filtration unit, activated carbon filtration unit, water softening unit, reverse osmosis unit, and polishing unit (EDI or mixed-bed).
- An unpurified pathway that directly feeds untreated water into the electrolysis cell.
- Operates with two parallel pathways, allowing real-time observation of how purified and unpurified water affects hydrogen production.
- Electrolysis Cells:
- Consist of two identical electrolysis cells made from durable, corrosion-resistant materials.
- Equipped with high-efficiency electrodes to ensure consistent hydrogen production.
- Features adjustable voltage and current
- Power supply controls for flexibility.
- Each cell processes water from its respective pathway, enabling direct comparison of hydrogen production outcomes.
- Continuous monitoring of water quality is achieved using conductivity and TDS meters before the water enters the electrolysis cells.
- Gas flow meters track the hydrogen production rate from each cell, providing data on efficiency.
- Hydrogen purity sensors assess the purity of the hydrogen produced, highlighting the impact of water quality on the final gas.
- Energy consumption meters monitor voltage, current, and total energy used in each cell, allowing users to evaluate the energy efficiency of each pathway.
- A digital display screen presents real-time data on water quality, hydrogen purity, production rates, and energy consumption, facilitating easy analysis and comparison.
- Interactive controls enable users to adjust power and water flow settings, enhancing engagement and experimentation.
