With many alternative energy options still in development, polymer electrolyte membrane (PEM) fuel cells are close to being the most efficient and sustainable.
Bipolar plates act as an anode for one cell and a cathode for the adjacent cell, which are ultimately stacked to form the membrane electrode assembly of a fuel cell.
Elcon offers stainless steel or titanium bipolar flow field plates with corrugated channels to enable liquids and gases to flow. Our photochemical etching capabilities can create precise and complex
grooves and crossover channels on both sides of the plate, with no stresses or burrs.
How PEM fuel cells work:
- Hydrogen fuel cells use hydrogen as fuel and oxygen to convert to electricity, with water and heat as by-products.
- At the anode, a catalyst causes the hydrogen to split into positive ions and negatively charged electrons. At the cathode, the electrons and positively charged hydrogen ions combine with oxygen to form water, a by-product of the fuel cell.
- The protons travel through the membrane, while the electrons flow through the circuit and create an electric current.
