What are the advantages of fuel power batteries?

Advantages of fuel power cells 1) Energy saving, high conversion efficiency, no petroleum fuel a) Except for the reforming of gasoline to produce hydrogen, other fuels (methanol, hydrocarbons, etc.) basically do not use petroleum fuels. The overall efficiency from the engine through the drive system to the wheels is about 11% for internal combustion engine vehicles. The actual efficiency of FCEV with hydrogen as fuel reaches 50% to 70%; the actual efficiency of FCEV with hydrogen as fuel after reforming reaches 34%. It can be seen that the actual efficiency of FCEV is much higher than that of internal combustion engine vehicles. b) The internal combustion engine has the highest efficiency near the rated power, and when it operates under partial power output conditions, the efficiency decreases rapidly. The efficiency of the fuel power cell can reach 60% under the rated power, and the operating efficiency can reach 70% under the partial power output condition, and the operating efficiency can reach 50-55% under the overload power output condition. The high efficiency varies with the power in a wide range, and the operation rate is high at low power, which is especially suitable for the requirements of automobile power performance. c) The internal combustion engine has a low overload capacity and is easy to stall during overload operation. The short-term overload capacity of the fuel power battery can reach 200% of the rated power, which is very suitable for the characteristics of the power performance of the car when accelerating and climbing. In summary, the energy saving of fuel power cells far exceeds that of internal combustion engines, and the stability and reliability are higher than that of internal combustion engines. 2) The emission of harmful gases in the exhaust gas of internal combustion engines is zero pollution. The pollution caused to the environment is the fatal disadvantage of internal combustion engine vehicles. Although various technical measures inside and outside the aircraft are adopted, only low pollution can be achieved. Level, due to the huge number of internal combustion engine vehicles, even low pollution has a huge impact on the global environment. The important product of fuel cell engines using hydrogen as fuel is water, which is zero pollution. The important substances produced by the fuel cell engine using hydrocarbons as fuel are water, carbon dioxide and carbon monoxide, which are ultra-low pollution. Out of the requirements for the environmental protection of the earth and the search for new energy sources, the fuel-powered cell engine is an ideal power device, and may gradually replace petroleum as an important energy source for vehicles. 3) The vehicle performance is close to the internal combustion engine. The specific power of the internal combustion engine is about 300W/kg. At present, the specific power of the fuel cell body is 700W/kg and the power density is 1000W/L. If including the reformer, purifier and auxiliary equipment of the fuel power cell, the specific power is 300-350W/kg, and the power density is 280W/L. In terms of energy, fuel power cells are similar to internal combustion engines, so their power performance can reach the level of internal combustion engine vehicles. 4) Simple structure and stable operation a) The energy conversion of the fuel power cell engine is completed in a static state, and the structure of the structure is simple. The production accuracy requirements are much lower than that of internal combustion engines. In particular, the proton exchange membrane fuel power cell has high energy conversion efficiency, can be started and operated at a low temperature of 80°C, and has low requirements on the heat resistance of the structural parts. Most of the structural parts are plate-shaped and pipe fittings, there are no moving parts and various friction pairs, and there are no failures caused by the wear of parts, and the repair and maintenance are convenient. b) The fuel power cell engine is composed of multiple single fuel power cells in series, which can be configured into a series of fuel power cell engine packs of various specifications, and can be assembled on vehicles of different purposes and models. On the vehicle, the specific conditions such as the utilization of the effective space of the vehicle can be allocated according to the axle load of the vehicle, and the general layout can be flexibly and maneuvered. c) During the operation of the fuel power cell engine, the noise and vibration are small, the heat dissipation system is much simpler than that of the internal combustion engine, and the thermal management system is simpler; the output should not be purified and silenced, and the entire fuel power cell system is easy to implement Automated system management.
