Test systems for low-power hydrogen fuel cell

A test system for a low-power hydrogen fuel cell, comprising:

• an anode hydrogen control component, a cathode oxygen control component, and a coolant circulation component;
• wherein
• the anode hydrogen control component includes a hydrogen supply pump and a proton flowmeter, the hydrogen supply pump is in communication with an anode side of a cell under test, and the proton flowmeter is in communication with an anode exhaust port of the cell under test;
• the cathode oxygen control component includes a blower, a pulse width modulation (PWM) duty cycle controller, and a cathode rotameter, the blower is in communication with a cathode side of the cell under test, the PWM duty cycle controller is electrically connected to the blower, and the cathode rotameter is in communication with a cathode exhaust port of the cell under test;
• one end of the coolant circulation component is in communication with a cooling chamber inlet of the cell under test, and the other end of the coolant circulation component is in communication with a cooling chamber outlet of the cell under test;
• a first-stage pressure reducing valve is further disposed between the hydrogen supply pump and the anode side of the cell under test;
• a second-stage pressure reducing valve is further disposed between the first-stage pressure reducing valve and the anode side of the cell under test;
• and
• an anode rotameter is further disposed between the second-stage pressure reducing valve and the anode side of the cell under test.
