- A portable medical refrigerator powered by proton-exchange membrane fuel cell (PEMFC) system and
cooled by thermoelectric cooler (TEC) cooling module was developed. The TEC cooling module
consists of four TECs, each heat sink for cold and hot side, and air cooling fans for both sides. The
power consumption and cooling capacity of TEC cooling module are 63 W and 11.5 W, respectively.
The PEMFC system consists of an air-cooled stack combined the oxidant and coolant flow, a hydrogen
supply subsystem with metal hydride canister, and a control unit subsystem for the management of the
system with DC-DC converter and battery. To analyze the performance of PEMFC system, the power
consumption of balance of plant (BOP) components, power charging consumption of battery, and power
output of PEMFC stack is measured by according to the external load rates. When the power output of
PEMFC stack is increased from 50 W to 200 W, the BOP efficiency of PEMFC system is increased from
25% to 67%, respectively.
