With fast refuelling, longer range, and only water as a by-product, fuel cell electric vehicles (FCEVs) powered by hydrogen may be in the early stages of implementation but are already showing a lot of promise. To safely implement this exciting technology, the risks of hydrogen flammability must be managed.
In this regard, leak testing of fuel cell components has become critical. Manufacturers may need to test the tightness of each individual bipolar plate – of which there can be around 400 in...
