What is the fuel cell of AIP?
Less external heat radiation. As the energy conversion process less energy loss, so the corresponding heat dissipation is also less, which effectively reduces the submarine's thermal radiation, reduce the enemy infrared detection equipment found the probability of less noise, fuel cell system due to direct energy Conversion, so there is no mechanical moving parts, so the work process is very quiet, can make the submarine in the navigation was excellent concealment.
The main technical advantages of fuel cell: energy conversion efficiency is very high, the fuel cell by electrochemical way directly to the chemical energy into electricity, eliminating the heat engine power generation must go through the complex conversion process, reducing the energy loss, the theoretical energy Conversion efficiency can reach 100%, the actual efficiency can reach 70%.
AIP power plant includes closed cycle diesel engine, closed cycle steam turbine, Stirling engine, fuel cell. Nuclear power hybrid propulsion system can also be regarded as AIP power plant.
