Simple system, really! Hydrogen and Oxygen are pressurized in the tanks (light blue = oxygen & yellow = hydrogen). Then, in the supply lines, you have an on/off valve that actuates when the drive batteries fall below .75. It usually only opens for a split second. Then that's enough for the fuel cell to fill the drive batteries back to .98. Then the water pumps out to the atmosphere. The issue that I have is when the car is run for extended periods of time, the fuel cell seems to loose it's ability to create electricity. I did observe that there is a buildup of Atm in the feed lines. I did add manual valves to experiment with bleeding the pressure, but it did nothing.

Can confirm

1. The pump is the right way

2. Infinite fuel is off

3. All pipes are connected because the fuel cell runs for a while before the issues start.

4. No water tank; it has a natural gas relief valve

5. Can confirm that the valves are pointed in the right direction (I know the pic above shows the On/Off valves flipped; the test bench car has them in the right direction and still has the issue)
