PEM Fuel Cell Unit

The PEM Fuel Cell Unit, has been designed to allow the students to understand the fuel cells technology, especially that of a proton exchange membrane fuel cell (PEM).

ATENG 11570 — PEM Fuel Cell Unit

Bench-top unit.

Anodized aluminum frame and panels made of painted steel.

Main metallic elements made of stainless steel.

Diagram in the front panel with distribution of the elements similar to the real one.

• Pressure regulator for the hydrogen inlet at the PEM fuel cell, range: 0 – 1 bar.
• Pressure regulator of the H bottle. Inlet at 200 bar and outlet at 5 – 50 bar.

Solenoid valve to supply H.

Purge solenoid valve.

• Suitable tubes and hoses for their use with H with a high safety factor, up to 210 bar.

• Load module: Rheostat: 22 R – 760 W.

• Battery and charger (12 V).

• Fuel cell stack:
  24 cells self – humidifying (do not require any type of external humidification).

• Rated power: 100 W.
  Integrated fan in the stack

• Instrumentation:
  Detail of the pressure regulator of the H
  Flow meter to measure the inlet H flow to the stack. bottle and hose 2

Pressure meter (manometer) to measure the H pressure at the stack inlet.

Temperature sensor type “J” to measure the temperature of the purge stream.

Temperature sensor type “J” to measure and control the temperature in the stack.

Current and voltage sensors.

• Safety measures and protections:
  Failure protection with solenoid valve at the stack inlet.
  Over current shut down.
  Low voltage shut down.
  Over temperature shut down in the stack.
  Hydrogen leakage detector (4 – 20 mA; IP65).
• Electronic console:
  Metallic box.
  Temperature sensors connectors.
  Selector for the temperature sensors.
  Digital display for the temperature sensors.
  Voltage digital display and current digital display.
  Cables and accessories, for normal operation.
