Analyze the difference between batteries and fuel power batteries

1. Fuel power cell is a kind of energy conversion device, which can only produce electricity when there is energy (fuel) input during operation. Generally, a battery is an energy storage device. It must first store electrical energy in the battery. It can only output electrical energy during work. Do not input energy during work, and no electrical energy will appear. This is the essential difference between fuel power batteries and ordinary batteries. 2. Once the technical performance of the fuel power cell is determined, the electrical energy that can be generated is only related to the supply of fuel. As long as the fuel is supplied, electrical energy can be generated, and its discharge characteristics continue. After the technical performance of the general battery is determined, it can only output electric energy within its rated range, and it must be recharged before it can be reused. Its discharge characteristics are intermittent. 3. The mass and volume of the fuel power cell body is not large, but the fuel power cell needs a set of fuel storage device or fuel conversion device and auxiliary equipment to obtain hydrogen, and the mass of these fuel storage devices or fuel conversion device and auxiliary equipment And the volume is much larger than the fuel power cell itself. During the working process, the fuel will gradually be consumed with the appearance of the fuel power cell electricity, and the quality will gradually decrease (referring to the limited fuel on the vehicle). Generally, the storage battery has no other auxiliary equipment. After the technical performance is determined, the quality and volume of the storage battery remain basically unchanged regardless of whether it is overcharged or discharged. 4. The fuel power battery converts chemical energy into electrical energy. Generally, batteries also convert chemical energy into electrical energy. This is what they have in common. However, when the fuel power battery generates electrical energy, the reactants that participate in the reaction continue to react. Land consumption is no longer reused, so it requires continuous input of reactive substances. Generally, the active material of a battery changes with the charging and discharging of the battery, and the active material undergoes reversible chemical changes repeatedly, and the active material is not consumed, as long as some electrolytes and other materials are added.
