Storage of electrical energy from wind energy with the aid of a rechargeable battery

Principle

Accumulators exist at different states of charge. Before you begin with the experiment, make sure that the accumulator's charge is low enough so that the glow lamp does not glow at the beginning of the experiment. If it glows, the accu can be discharged rather quickly via the ...

Generation of hydrogen and oxygen using a PEM electrolyser

Principle

The PEM electrolyser consists of a thin, proton-conducting polymer electrolyte membrane (PEM), the two sides of which are each coated with a catalysing material. These coatings form the anode and the cathode. The theoretical decomposition voltage of water is 1.23 V. This voltage ...

Generación de energía eléctrica mediante el uso de celdas de combustible tipo PEM

Principle

All fuel cells fundamentally consist of two electrodes (cathode and anode) and an electrolyte which separates the two electrodes from each other. The mode of operation corresponds to a reversed electrolysis. Fuel cells are classified according to the type of electrolyte. Their ...

Solar-hydrogen system



Principle

Whereas coal, natural gas and crude oil sources will be exhausted in the not too distant future, the sun is expected to continue to exist in the form known to us for about 5 billion years. Solar energy can be utilised, but is not always available when it is needed. It ...

Wind-hydrogen system

Principle

Similarly to solar energy, wind energy is a regenerative form of energy. It differs in that it has been used by man for centuries, for example, in windmills, in which it is converted to mechanical energy. In recent times, wind power plants have been brought to use for the ...

Characteristic curve of a PEM electrolyser

Principle

The PEM electrolyser consists of a thin, proton-conducting, polymer electrolyte membrane (PEM). The two sides of this are each coated with a catalysing material and act as anode and cathode. The theoretical decomposition voltage of water is 1.23 V, but it is higher in practice ...

Faraday efficiency and energetic efficiency of a PEM electrolyser

Principle

The efficiency of an electrolyser is an indicator of the efficiency of energy conversion. A differentiation is made here between energetic and faradic efficiencies.

When a new technology is developed, it is important that it can be economically utilized. If the efficiency is ...

Current-voltage characteristic of a PEM fuel cell

Principle

The performance curve of a PEM fuel cell is not linear, but reaches a maximum performance at a certain current. When fuel cells are used in practice, it is important that they are operated with the current at which the fuel cell brings the most power.

Fuel cells are ...

The efficiency of a electrolyser-fuel cell system

Principle

The use of hydrogen and oxygen for energy storage only makes sense when it functions with the lowest possible losses.

In this experiment, an examination is to be made on the efficiency of an electrolyser - fuel cell system and consequently on the total efficiency of the chain ...
