In this study, experimental constant-current cold starts were performed on a polymer electrolyte fuel cell from −10°C to characterize high-frequency resistance behavior, water motion, and ice accumulation before, during, and after cold start. A diagnostic method for rapid and repeatable cold starts was developed and verified. Cold-start performance is found to be optimized when cell resistance ...

Abstract In this study, the implementation of a hydrogen microgrid is investigated, considering integration H 2 production, storage, and energy conversion to feed typical end-user. A remote control system has been realized through LabVIEW software, allowing monitor real-time all devices analyze their performances. The integrated composed PEM electrolyzer (325 W ), storage based on metal hydride...

The proton exchange membrane (PEMFC) fuel cell represents the energy of the future, in parallel with hydrogen. However, this technology must meet many technical challenges related to performance and durability before being sold on a large scale. It is well known that these challenges are closely linked to water management. This paper develops and implements a model of PEM fuel for simulation to...

This study presents an experimental stack-level thermal and hydrodynamic assessment of a model air-cooled PEM fuel cell. To mimic the heat generation inside the MEA, rubber heater films are used. Pressure drop along the stack channels and temperature distribution on the bipolar plate surface are measured for the channel Reynolds number range of 200-500 and the stack input power range of 100-250...

Combined plant/control optimization is applied to a PEM hybrid fuel cell vehicle (HFCV) for vehicle to grid (V2G) applications. The HFCV model is developed from past control-oriented models. For the purposes of design optimization, three components (fuel cell stack, compressor, and battery) are made scalable. To construct a control scheme suitable for combined plant/control design optimization,...

A control-oriented dynamic model of a catalytic partial oxidation-based fuel processor is developed using physics-based principles. The fuel processor system (FPS) converts a hydrocarbon fuel to a hydrogen (H2)-rich mixture that is directly feed to the proton exchange membrane fuel cell stack (PEM-FCS). Cost and performance requirements of the total powerplant typically lead to highly integrate...
