tüzelanyagcellákban
Tüzelanyagcellákban, or fuel cells in Hungarian, are electrochemical devices that convert chemical energy from a fuel into electricity through a chemical reaction with an oxidizing agent. Unlike batteries, fuel cells do not run down or require recharging; they produce electricity and heat continuously as long as fuel and an oxidizer are supplied. The most common fuel is hydrogen, and the oxidizer is oxygen, typically from the air.
The fundamental principle of a fuel cell involves two electrodes, an anode and a cathode, separated by
Various types of fuel cells exist, differentiated by their electrolyte and operating temperature. Common types include
