Tech Tips

Fuel cells are an extremely active field of research.
They generate electric energy by producing water from hydrogen and oxygen. Fuel cell vehicles, which use this electric energy for power, are very good for the environment because they release only water vapor and no exhaust gas.

Fuel cells are also being considered for use for electric power in the home and office environments. In such cases, electricity would be generated in the places where it would be used, so there would be no loss during the transmission of power, as occurs in conventional applications where electricity is sent from a power plant. Furthermore, the heat that is generated when water is produced can be used to supply hot water and thereby improve the efficiency of energy usage.
The day may come in the near future when there are no longer any power plants or telephone poles.

Electronic loads are effective for evaluating fuel cells. At the same time, programmable DC power supplies and other types of power supplies are used to evaluate equipment such as motors, electric motors, and lamps that use electric energy generated by fuel cells.

Photovoltaic cells generate power from light, and in the same way electronic loads, bipolar power supplies/power amplifiers, and programmable DC power supplies are useful for performing evaluation tests.
