Programmable Power Supplies for Simulating Fuel Cell Characteristics
In any application that utilizes hydrogen fuel cells, it is essential for engineers to first create a test environment to monitor important metrics, such as cell fuel, temperature, pressure, supply, and exhaust air.

Application Note Overview
In any application that utilizes hydrogen fuel cells, it is essential for engineers to first create a test environment to monitor important metrics, such as cell fuel, temperature, pressure, supply, and exhaust air. This test helps to reduce the preparation time in the R&D phase, speeding up the time to market for new products. The “FC” (Fuel Cell) function on the EA Elektro-Automatik power supply is used to accurately simulate the I-U curve of a fuel cell.
This application note by EA Elektro-Automatik outlines the use of programmable power supplies for simulating fuel cell characteristics in custom applications. EA Elektro-Automatik’s power supply series PSI 10000 and PSB 10000 feature an IU function based on an XY generator. They allow users to program a power supply to set a DC current depending on the actual voltage on a DC terminal.
