Energy Storage - Electrolyzer / Fuel Cell

Background

Like the stored chemical energy in the two components, gasoline and oxygen, that power a car, it is possible to use other chemical pairs. The combination of hydrogen and oxygen has several main advantages: The two components are easily produced by the electrolysis of water using electrical energy. The chemical reaction to get back the stored energy produces only pure water. It is possible to construct a fuel cell which enables the "cold burning" of the two components to directly produce electricity. The related Hydrogen(-Oxygen) Technology has the potential to replace fossil-fuel energy with a renewable storage technology that uses renewable solar energy sources like wind-power and photovoltaic systems to produce stored chemical energy for on-demand electricity generation.

FuelCellH2Air - PEM Fuel Cell for Hydrogen / Air Operation

A fuel cell converts the stored chemical energy within hydrogen / oxygen directly into electric energy. It is like a cold burning of hydrogen and oxygen back to water. The key component of the PEM (Polymer Electrolyte Membrane) fuel cell is the MEA (Membrane Electrode Assembly). This is of a Polymer membrane coated on opposite sides with two catalysts that form the anode and cathode of the cell. The basic idea is that the Polymer membrane only conducts positively charged Hydrogen protons (PEM - Proton Exchange Membrane) from the anode catalyst to the cathode catalyst where they combine with Oxygen to form water. So you have a generator with a "charge separation" on the anode and a charge neutralization on the cathode. For the process to work, and in a control manner, there must be an external flow of (hydrogen) electrons via an electrical circuit from anode to cathode. In other words the chemical engine directly generates electricity without any moving parts.

LexsolarH2ReadyToGo - Hydrogen Fuel Cell Experimental Kit

leXsolar-H2 Ready-to-go offers the entire scope of the latest experiments in fuel cell technology for the classroom. With a solar panel, electrolyzer, and fuel cells, a solar-hydrogen-circuit can be set up and analyzed. On the other hand, the students also have the possibility of researching each single component. Working principles, efficiency, and the characteristic curves of electrolyzers and fuel cells are just some of the possible topics. With the included consumer modules younger students (from 12 years up) are also able to run simple basic experiments. Besides the PEM-fuel cell (PEM = polymer electrolyte membrane) a methanol-fuel cell is included, which can use methanol instead of hydrogen as fuel. That is why this fuel cell also has a high practical relevance. Furthermore, additional experiments such as working with different membranes or a comparison of the operating mode of fuel cells with air and hydrogen as well as hydrogen and oxygen, can be displayed. True to the tradition of the Ready-to-go line all ancillary equipment are already included in the robust aluminum suitcase.

Solarfuel - Electrolyzer for Hydrogen and Oxygen Production, with Water Tanks and Gas Storage

The key component for a Hydrogen storage system. Pure distilled water is split by electrolysis with an electric current into hydrogen and oxygen. The electrolyzer is made of a Polymer Electrolyte Membrane between two catalytic electrodes acting as anode and cathode. It does not require any caustic electrolytes. The Solarfuel includes two gas storage cylinders and water containers and is assembled on a base plate. The generated hydrogen and oxygen can be used to drive a fuel cell and generate electricity.
Technical Data:
  • Dimension 20cm x 12cm x 9cm
  • Voltage 0 - 2,0 V
  • Current 0 - 2,0 A
  • Gas Production H2 / O2 8,6 / 4,3 cm^3/min
  • Storage Volume 20 cm^3
