Hardware-in-Loop (HiL) methodology is well established in the automotive industry, where the hardware element is typically a controller and the HiL technique is applied to develop and debug control algorithms for automotive drive systems. In contrast, this paper is focused on the use of a new HiL methodology (Fuel Cell HiL) for experimental fuel cell evaluation. In this methodology a fuel cell is experimentally evaluated within the context of a fuel cell system design, an application (e.g., a fuel cell vehicle), and for a typical use pattern (e.g., a standard drive cycle).

“…A proprietary 36 cells stack with an active area of ~21 cm 2 and active section length of ~11 cm was used. The stack was operated with a custom test station designed for hardware-in-the-loop measurements characterized by a dynamic response time 0.1 s (11,12). Operating conditions respectively were: air/H 2 , 2.5 stoichiometry/dead end, 75/0 % relative humidity, ambient/ambient pressure outlets, 55 C, 1 A cm 2 .…”

A PEMFC stack was contaminated with 50 ppm propene in air. The average performance decreased by 243 mV until a steady state was reached. After the propene injection was interrupted, the average performance increased until a new steady state was attained that exceeded the initial value by ~6 mV. Propene contamination amplified the uneven cell performance distribution along the stack length. End cells showed a larger performance change than the other cells with respect to the pre-contamination phase of respectively 24 and 15 mV. The effect was ascribed to interactions between propene and the uneven temperature distribution. Propene contamination affects both oxygen reduction kinetics and mass transfer as revealed by impedance spectroscopy measurements.

“…Considering all requirements, a new stack test station was tailored as an extension and advancement to the single cell testing system introduced in previous work (3). In order to avoid the disadvantages illustrated above, the core component is a self contained real-time controller that incorporates the entire test station strategy.…”

Modeling, HiL-simulation and dynamic prototype validation becomes more demanded as the diversity and complexity of fuel cell applications increases. Particularly the high dynamics of automotive employment and a reduced time-to-market are fertile ground for dynamic models. The testing and simulation system introduced in this paper is a tool that supports every step of fuel cell stack development, from modeling in the early design phase to end-of-line testing. As traditional testing methodology does not account for high system dynamics, transient analysis and deterministic simulation, a new concept was designed from scratch. Based on self-contained, inherently safe real-time controller and a high speed cell diagnosis system, this tool helps to derive model parameters from dynamic measurements, co-simulates the model with the physical unit, easily adapts to different testing scenarios and allows conceiving end-of-line product validation.
