“…Whilst heat pipes have been shown to be effective for passive heat removal from small fuel cell stacks [24], the required condenser areas and short pipe lengths make current designs better suited to heat spreading in low power applications. Flow boiling with application to PEM fuel cells has been experimentally studied by Garrity et al and Soupremanien et al [25,26].…”

Available online xxxKeywords: Thermal management Water balance Fuel cell vehicle PEM Heat transfer Cooling a b s t r a c tDespite having efficiencies higher than internal combustion engines, heat rejection from fuel cells remains challenging due to lower operating temperatures and reduced exhaust heat flow. This work details a full system simulation which is then used to compare a conventional liquid cooled fuel cell system to two types of evaporatively cooled fuel cell systems. Both steady state and transient operation are considered. Results show the radiator frontal area required to achieve thermal and water balance for an evaporatively cooled system with an aluminium condensing radiator is 27% less than a conventional liquid cooled system at 1.25 A/cm 2 steady state operation. The primary reason for the reduction is higher heat transfer coefficients in the condensing radiator due to phase change. It is also shown that the liquid water separation efficiency has a significant influence on the required radiator frontal area of the evaporatively cooled system.

“…The latent heat is usually very higher than the sensible heat absorbed by the coolant [8,18]. Silva et al [19] developed a two-phase heat transfer cooling system consisted of a capillary pumped loop (CPL) with heat pipes as an alternative for the liquid cooling system. The proposed system removed heat successfully for power inputs up to 50 W, maintaining the operation temperature of stack in the range from 70 to 90 C. However the coupling of the proposed system to a real fuel cell was not conducted.…”

“…A Hydrogen Fuel Cell (FC) is an electro-chemical device that converts the chemical energy of hydrogen or a hydrogen rich fuel into electricity through a chemical reaction with oxygen or another oxidizing agent [1][2][3][4]. Due to their particular advantages fuel cells have already started to create a revolutionary change in the way electrical energy is stored [5].…”
