Tandem Technologies manufactures all flowfield plates in-house to high standards using high quality fuel cell grade graphite materials.

The standard flowfield which was introduced in 2010 is semi-coflow. The reactants run counterflow at the channel level but coflow at the overall flowfield level

We can produce custom flowfield plates that are fully compatible with TP50 hardware. Groove widths to 0.016" (0.4mm)
