  1. Electrolysers for Hydrogen Production by Peter Sudol

  2. Methods of Hydrogen Production

  3. Uses of the Water Electrolysis • Submarines, space stations (generation of breathing oxygen) • Medical, chemical and other special applications • In great quantities, economic only in those regions of the world where electric power can be generated very cheaply. This is the case almost exclusively in big hydroelectric plants (e.g. in Egypt, Iceland, Norway..). • In the increasing renewable energy market, Water Electrolysis can be used for compensation of the differences between the demand and supply of energy from the variable renewable energy resources.

  4. Hydrogen pipeline project in Totara Valley Fuel Cell Pipeline 2km Wind Energy Electrolyser Hydrogen Burner

  5. Types of Water Electrolysis

  6. PEM Electrolyser (two cells)

  7. Principle of a PEM electrolysis cell

  8. Nafion - Membrane hydrophilic (polar) hydrophobic (nonpolar) sulfonated polytetrafluorethylene

  9. UI characteristic curves of an electrolyser Cell Voltage [V] Current density [mA/cm2]

  10. UI characteristic curves of an electrolyser Cell Voltage [V] Current density [mA/cm2]

  11. UI characteristic curves of two electrolysers Cell Voltage [V] Current density [mA/cm2]

  12. Further Steps in the Research Project • Simulating the distributed energy system in the laboratory • Determination of the efficiency of the whole system • Optimisation of the efficiency • Observing the performance of the electrolyser at different temperatures, different pressures, different inputs • Observing the distribution and pressure of Hydrogen in the pipeline • Observing the performance of the fuel cell
