The development history of fuel-powered battery vehicles has been ups and downs several times

In 1838, the German chemist Christian u0026middot; Friedrich u0026middot; Shangban proposed the principle of fuel power cell; in 1991, Roger u0026middot; Billing developed the world's first fuel power for automobiles Batteries; in 1992, with the support of the government, automobile manufacturers in various countries began to vigorously develop fuel-powered battery vehicles; in 1994, the world's first fuel-powered battery car u0026mdash; Mercedes-Benz NECARI came out; in 2013, Toyota exhibited at the Tokyo Motor Show FCV concept car, and announced the 2015 mass production version. From these short lines of words, we can't know how hard this is about to come out of the mass production version of the fuel cell vehicle. However, only time can get a glimpse of the iceberg. It took only three years from the advent of fuel-powered batteries for automobiles to the advent of the first car, and from the advent of the first fuel-powered battery car to a vehicle that can give a precise listing time, it has gone. Nine years. In the past nine years, fuel-powered battery vehicles have experienced ups and downs. Every once in a while, fuel-powered battery vehicles will bring a major breakthrough in a certain technology to sharpen their sense of existence. However, those unsolved problems always make people question him more than they support it, so, It was pressured back by the talk of hybrid and pure electric vehicles. Automakers represented by Toyota have become more and more frustrated. In addition to Toyota’s announcement of a clear timetable, BMW has signed a cooperation agreement with Toyota to jointly advance fuel cell research; Honda will also launch the next-generation FCXClarity in 2015; Hyundai plans to start California’s ix35 lease in the spring of next year. Project; Ford, Daimler, and Nissan have joined forces, and the initial launch time is set for 2017; GM, the first to enter the field of fuel-powered batteries, also teamed up with Honda, and some products will come out in 2015-2017. The appointment of hydrogen and oxygen. Structurally, the composition of the power system of a fuel-powered vehicle is very similar to that of a hybrid vehicle. The difference is that the engine on the hybrid vehicle is replaced with a fuel-powered cell stack; On the other hand, fuel cell vehicles are more similar to internal combustion engine vehicles. The difference is that internal combustion engine vehicles convert heat energy into mechanical energy to drive the vehicle, while fuel cell vehicles use fuel power cells to generate electricity and then convert electrical energy into mechanical energy. The working principle of fuel power battery is very simple. The fuel power cell consists of three adjacent sections of anode, electrolyte and cathode. Between two adjacent sections, a chemical reaction will occur—hydrogen will undergo oxidation at the anode and oxygen will undergo a reduction at the cathode, thereby consuming fuel, generating current, and driving the electrical equipment loaded on the system, including motors, In-vehicle equipment and components, etc. In order to supply the required output energy, what is used in the car is a fuel-powered cell stack composed of fuel-powered batteries. Compared with batteries on electric vehicles, fuel-powered battery stacks have a great advantage in weight. In addition, due to the built-in power generation equipment, fuel-powered battery vehicles do not need to obtain electricity from the grid, as long as they replenish their fuel at an appropriate time, so there is no common problem of electric vehicles u0026 mdash; mileage anxiety.
