What are the advantages of fuel-powered batteries?

(1) Energy-saving, high conversion efficiency, no petroleum fuels (1) Except for the reforming of gasoline to generate 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, and the actual efficiency of FCEV using hydrogen as fuel reaches 50% to 70%. Using methanol as fuel, hydrogen FCEV appears after reforming, and the actual efficiency reaches 34%. The actual efficiency of FCEV is much higher than that of internal combustion engine vehicles. ②The internal combustion engine has the highest efficiency near the rated power, and when it runs under partial power output conditions, the efficiency drops rapidly. The efficiency of the fuel-powered battery can reach 60% under the rated power, and the efficiency can reach 70% under the condition of partial power output, and the operating efficiency can reach 50% to 55% under the condition of overload power output. The high efficiency varies with the power in a wide range, and the operation efficiency is high at low power, which is especially suitable for the requirements of automobile power performance. ③The 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. It is very suitable for the characteristics of the dynamic performance of the car when accelerating and climbing. Based on the above points, the energy saving of fuel power batteries 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 from internal combustion engines is zero pollution. The pollution to the environment is a fatal shortcoming of internal combustion engine vehicles. Although various technical measures inside and outside the engine are adopted, only low pollution can be achieved. Due to the large number of internal combustion engine vehicles, even low pollution has a huge impact on the global environment. The important substances produced by fuel-powered battery engines that use hydrogen as fuel are water and CO2, which are zero pollution. The most important substances produced by fuel-powered battery engines that use hydrocarbons as fuel are water and CO2, 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 battery 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 power battery body is 700W/kg and the power density is 1000W/L. If including the reformer, purifier and auxiliary equipment of the fuel-powered battery, the specific power is 300-350W/kg, and the power density is 280W/L. In terms of energy, the fuel-powered battery is close to the internal combustion engine, so its power performance can reach the level of an internal combustion engine car. (4) Simple structure and smooth operation ① The energy conversion of the fuel power battery engine is completed under static conditions, the structure of the structure is simple, and the production accuracy requirements are much lower than that of the internal combustion engine. In particular, the proton exchange membrane fuel power battery has high energy conversion efficiency, can be started and operated under low temperature conditions, and has low requirements on the heat resistance of 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. ②The fuel power battery engine is composed of multiple single fuel power batteries in series, which can be configured into a series of fuel power battery engine sets of various specifications, and can be assembled on vehicles of different purposes and models. The vehicle can be arranged flexibly and flexibly according to specific conditions such as the distribution of the axle load of the vehicle and the utilization of the effective space of the vehicle.
