A fuel cell is a device that generates electricity by directly converting the chemical energy of a fuel, such as hydrogen, through what type of process?

Explanation

A fuel cell is a device that generates electricity by directly converting the chemical energy stored in a fuel, commonly hydrogen, into electrical energy through an electrochemical reaction, notably without relying on direct combustion, or burning, of the fuel as would occur in a typical engine. In a common hydrogen fuel cell, hydrogen and oxygen react at separate electrodes to produce electricity, with water being the primary byproduct of the overall reaction. Because this process avoids traditional combustion, fuel cells are often explored as a potentially cleaner alternative energy technology for various applications, including certain types of vehicles.
