Fuel Cell Electrical Test

Perform electrical tests on your fuel cell or fuel cell stack using DC electronic loads and power supplies

Fuel Cell Electrical Test Image

A fuel cell is an electrochemical device used to create electricity through a reaction between a fuel (such as hydrogen) and an oxidant (such as oxygen) in the presence of an electrolyte. In addition to producing electricity, the reaction generates byproducts, which typically are only water and heat. Therefore, using fuel cells is an environmentally friendly way to produce electricity.

Typical fuel cell electrical testing requirements include:

  • Draw DC current − to load the fuel cell or fuel cell stack
  • Measure DC voltages, DC currents, and temperatures − monitor individual cell performance in a stack to identify deviations in the fuel cell assembly process
  • Measure AC impedance − to identify kinetic and ohmic resistances, uncovering efficiency issues by revealing internal cell losses
  • Electrochemical Impedance Spectroscopy (EIS) − measure impedance across a range of frequencies to identify problems with fuel cell components
