Measuring the performance of the fuel cell and the fuel cell compares to other power generation devices, some technical indicators or parameters are used, including current density, power density, life, cost, and efficiency.1, current density. The key indicator of a single fuel cell is the current density, that is, the current intensity (MA / CM2) on the unit electrode area. However, it is to be noted that the current strength of the fuel cell is not proportional to the electrode area, and the electrode area is doubled, and the current intensity does not double. The cause is more complicated, related to factors such as the type of fuel cell and the design of the battery.
2, power density. The W-based power supply has a certain power, weight and volume. Key indicators are power density and specific power. Quality specific power (W / kg) is also known as quality power density.
3, life. The life of the fuel cell usually refers to the accumulation time of the power supply. When the fuel cell cannot output a rated power, its life is ended. For example, a fuel cell power supply of a rated power is 1KW, and the output power at the factory is generally 20% higher than the rated power, namely 1.2 kW. When the output power of the power supply is less than IKW, it is invalid. Thousands of hourly voltage drops are also used to make the life of the fuel cell.
4, cost. The cost of fuel cells is the most important indicator of the application.
5, efficiency. Like other power generation devices, efficiency is an important indicator of fuel cell power. Efficiency is closely related to energy utilization, and it is especially important in today's weakness.
In the automotive industry, two of the most important technical indicators are cost and power density. The cost, power density and life of modern cars are 10 US dollars / m, 1 kW / l, 4000H, respectively. If you run LH every day, its life is 10 years. For fuel cells, the electric power plant is combined, the cost should be controlled at 100 (] USD / KW or less, the life is not less than 40000h.
