From hydrogen and oxygen to fuel cell

The first fuel cells were invented in 1838 but they were not used commercially until the NASA space program developed a program using fuel cells to generate power for satellites and space capsules. Discover in this article how the MASS-VIEW® can be used to create a fuel cell.

Fuel cells convert chemical energy into electricity through an reaction of (usually) hydrogen and oxygen.


Working principle

In contrast to a battery, where a reaction of chemicals present in the battery occurs, fuel cells need a continuous source of fuel and oxygen to produce energy. As displayed in the picture above, a fuel cells consists of an anode, a cathode and an electrolyte in which positivily charged hydrogen move between the two sides of the cell. An oxidation process commences in the anode that generates protons and electrons. The protons that were developed flow from the anode to the cathode. Direct current electricity is produced through the process of protons flowing from the anode to the cathode through the electrolyte and the electron moving from the anode to the cathode through an external circuit. In the cathode a catalyst causes hydrogen, oxygen, and electrons to react to form water.

Practical application of the MASS-VIEW

At Mass Flow ONLINE we offer innovative standard solutions for many different applications across many different markets. Our instruments are used in various environments the biggest of which are laboratory, industrial and hazardous areas. Through years of experience we have developed a wealth of knowledge and created a world-wide reputation for the high quality of our products.
A wide variety of MASS-VIEW meters, regulator and controllers can be used to build fuel cells. Some of the benefits of the MASS-VIEW are listed below:

  • MASS-VIEW meters / regulators / controllers are available in wide flow ranges from 10 – 200 mln/min up to 1 – 500 ln/min.
  • Possibility to control a variety of gases, like Air, N2, O2, CO2, CO, N2O, Ar, CH4, C3H8 and C4H10.
  • Special designed MASS-VIEW equipment that is suited for H2.
