Fuel cells are used in many applications, from personal use to energy generation stations. The fuel cell ^{systems consist of a fuel cell stack, and its components to control air, H}2 ^{O, thermal and electrical power.} The entire system is efficient at maximum and half load, scales to a variety of sizes, is eco-friendly and has potentially comparable initial costs to conventional technologies. Portable electricity, mobility, cogeneration in buildings, and distributed electricity for utilities are promising applications for fuel cells. The vital barriers to the money orientation of fuel cells are pricing and longevity. We will talk about fuel cells, the classification of fuel cells, fuel cell problems, and how artificial intelligence can help improve the performance of fuel cells.
