A patented liquid catalyst developed by ACAL Energy has enabled a PEM hydrogen fuel cell to reach 10,000 hours runtime on an automotive industry durability test without significant signs of degradation.
10,000 hours, the equivalent of 300,000 driven miles, is the point at which hydrogen fuel cell endurance is comparable to the best light-weight diesel engines under such test conditions.
This endurance exceeds the current 2017 US Department of Energy industry target for fuel cell powered vehicles to last 5,000 hours, equivalent to 150,000 road miles, with an expected degradation threshold of approximately 10 per cent.
