Accurate Testing and Flexible Simulation
Our regenerative loads feature a full range of capabilities that enable fast and accurate testing of fuel cell resistance, as well as fuel cell performance and lifespan, offering a high cost-performance ratio. Our bidirectional laboratory power supplies can also simulate the characteristics of different fuel cells, providing greater flexibility and reducing operational costs with just the press of a button. Our solutions are versatile, allowing you to test and simulate fuel cells for all common applications using EA equipment, such as industrial trucks, transportation vehicles, long-haul trucks, and emergency generators. This is particularly important as the fuel cell market is currently growing at a rate of 30% due to government plans, economic incentives, and new applications.
Testing
Looking to quickly test the resistance, performance, and lifespan of fuel cells while saving costs? The EA-ELR 10000 series regenerative loads, with an input power of 30kW, are the ideal tool for testing fuel cells. For large-scale testing, they can be linked to achieve up to 1.92MW. Built-in arbitrary waveform generators and function generators, along with true self-adjusting capabilities, ensure maximum testing flexibility. Additionally, due to the regenerative operating mode, energy is not lost but returned to the power grid with an efficiency of over 96%. This not only saves on electricity but also eliminates the need for expensive additional cooling systems.
The EA-PSB 10000 bidirectional power supply is also suitable for testing fuel cells, with the same power capabilities.
Simulation
If you want to test the performance and characteristics of various fuel cells in the simplest, fastest, and most cost-effective way possible, our EA-PSB 10000 bidirectional power supply is definitely the ideal choice. It can accurately simulate various fuel cells and their specific characteristics. With a power of 30kW, which can be increased to 1.92MW in parallel, it can also simultaneously simulate particularly powerful or multiple fuel cells.
As a bidirectional solution, the EA-PSB can be used as a load and for testing fuel cells. Thanks to energy recovery, the absorbed energy can be returned to the power grid, with an efficiency of over 96%.
Fuel Cell Stack Performance Testing Simulating Different UI Characteristics
The polarization and power density curves of fuel cell stacks are commonly used indicators for measuring battery performance. These curves are typically evaluated under the optimal working conditions of the fuel cell stack (temperature, humidity, electrocatalysis, and ion exchange membrane).
By programming the DC load with different current or resistance curves, these measurements can be easily obtained. The ELR 9000 3U/9000 HP/10000 4U series electronic loads from EA ElektroAutomatik provide a variety of dynamic load tests for fuel cell characteristics.
Constant Resistance Mode Users can set a target resistance value to draw the required current from the stack. The resistance can be easily adjusted through an intuitive human-machine interface (HMI).
XY Chart Users can define different load currents for different voltages by loading an IV chart into the product. This is particularly suitable for verifying non-linear output characteristics.
Fuel Cell Stack Durability Testing Aging Testing
As an active energy source for various applications, fuel cells must undergo durability testing to ensure the safety and stability of the product. Generally, automotive industry testing standards require 5000 hours (about 7 months), while stationary energy storage applications may even need more than 10,000 hours. To shorten the durability testing time, potential step and triangular wave potential cycling are commonly used. However, for a typical 100kW fuel cell stack system, this still represents a significant operating cost.
To optimize energy usage, more and more fuel cell testing stations are equipped with regenerative DC electronic loads that return electricity to the local power grid, effectively returning operating costs to the factory owner. The ELR 9000 3U/9000 HP/10000 4U series electronic loads from EA ElektroAutomatik have a high regenerative efficiency, saving both energy and costs.
In addition, users can use the built-in function generator of the ELR series to run accelerated test profiles (steps or triangular waves). The discharge test function also provides additional energy measurement results.
