How does a fuel cell work?

A fuel cell is a device for directly converting the chemical energy of fuel combustion into electrical energy, which first appeared in 1955.

Energy is released during the "cold combustion" of hydrogen in oxygen, and the product of the reaction is water, and the energy is obtained in the form of an electric current. There are many examples of electric vehicles using this principle.

Fuel cells are an environmentally friendly source of energy, and it is hoped that over time they will be used more and more widely.

Random interesting fact from the Great Encyclopedia:

Which country is the leader in the number of its different names in different languages?

The names of countries can differ radically in different languages, and Germany can be considered the leader in this indicator. In Russian, English and several other languages, this name comes from the Latin words for "man" and "spear". In French, Spanish, a large group of Turkic languages, this country bears the name Alemannia from the Alemannic tribe, with whom those peoples encountered more often than other Germanic tribes. Similarly in Estonian and Finnish - Saksamaa and Saxa, from the tribe of Saxons. In most Eastern European Slavic languages, the country is called Nimechchina, Nemechko, etc., which comes from the concept of "German", figuratively "mute, not speaking our language." Finally, in Germany itself and all the Scandinavian languages, the country is called Deutschland or close to it, which simply means "country of the people."

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Radio receiver VICTOR RA-BF3 with sound delay system 25.08.2004

The Japanese company Victor Company of Japan, known in Russia by the JVC trademark, has released a new Victor RA-BF3 radio receiver with a sound delay system.

A little earlier, the same company introduced a TV with a similar system. NHK's proprietary audio slowdown system improves speech intelligibility, particularly in radio news broadcasts. The received sound is recorded in the built-in buffer, after which it slows down, deciphering the "patters" of the speakers. The system automatically monitors the duration of pauses in programs and adjusts the speed of audio playback.

The Victor RA-BF3 model is capable of receiving radio broadcasts in the FM and AM bands, as well as the sound of television broadcasts in the meter range. The receiver has an analog tuning system and features large buttons for ease of use.

The device reproduces monophonic sound, has a built-in 10 cm loudspeaker and a headphone output; amplifier power 800 mW. There is a 60 minute shutdown timer.
