“…The H 2 working capacity is more useful than the H 2 adsorption capacity once the pressure-swing adsorption (PSA) process is adopted. The H 2 storage pressure in the fuel storage tank is 35 000 kPa, , which can be treated as the maximum adsorption pressure. The fuel cell operating pressure generally remains at 160 kPa, which can be minimum desorption pressure in the fuel storage tank. , Therefore, the PSA capacity (Δ q ) is defined as the difference between the H 2 gas adsorption capacity at the maximum adsorption pressure ( q a ) and minimum desorption pressure ( q d ) at 298 K. …”

Thermal management of H2 gas storage in a tank is crucial for determining the H2 gas deliverable capacity. In this study, a strategy for the design of an excellent comprehensive performance fuel storage tank from the screening of microscopic materials to the design of macroscopic particle adsorption tank performance is proposed. The best metal–organic framework (MOF) for H2 deliverable capacity in a computation-ready experimental MOF database is first screened using a grand canonical Monte Carlo (GCMC) method. An upscale model that combines the finite volume method with GCMC is then established to investigate the H2 charging and discharging processes in a screened best MOF-filled adsorption particle tank that is integrated with a phase-change material (PCM) jacket. The process of the heat and mass transfer in the screened best MOF particle adsorption tank with and without the PCM jacket-inserted metal foam is studied. The results show that the prescreened XAWVUN has the highest gravimetric and considerable volumetric deliverable capacity among 503 MOFs, which can reach up to 23.1 mol·kg–1 and 20.8 kg·m–3 at 298 K and pressures between 35 000 kPa (adsorption pressure) and 160 kPa (desorption pressure), respectively. The H2 deliverable capacity can be maximized by 3.2 and 12.1% for PCM jackets inserted with metal foam in the H2 charging and discharging processes when it is compared with the case without the PCM jacket, respectively. The above study will facilitate the development of new equipment for hydrogen storage.

“…En la mayoría de los estudios, el regulador de presión mecánica se implementa para modular la presión de hidrógeno. Pero cuando la carga cambia o se activa la operación de purga, la presión de hidrógeno aguas abajo del regulador varía con la fluctuación del flujo de hidrógeno [24].…”

“…The control of the reactants supply is of relevant importance for conceiving PEMFC power systems. Fang, 2015 [8], for example, modeled a hydrogen injection subsystem, consisting of gaseous fuel injectors that offer greater flexibility for controlling the anode pressure, and consequently for compensating abrupt pressure reduction when purge occurs. But a major concern in the system management is the air supply subsystem; herein the problems of oxygen excess ratio regulation, equalization of anode and cathode pressures and water management control are essentially addressed in PEMFC control studies using a variety of techniques, e.g., nonlinear model-based predictive control of gas pressures was applied to deal with different events of errors in PEMFC systems, along with several types of dynamic load changes [9,10].…”

Control of the Air Supply Subsystem in a PEMFC with Balance of Plant Simulation

et al. 2017

This paper deals with the design of a control scheme for improving the air supply subsystem of a Proton Exchange Membrane Fuel Cell (PEMFC) with maximum power of 65 kW. The control scheme is evaluated in a plant simulator which incorporates the balance of plant (BOP) components and is built in the aspenONE R platform. The aspenONE R libraries and tools allows introducing the compressor map and sizing the heat exchangers used to conduct the reactants temperature to the operating value. The PEMFC model and an adaptive controller were programmed to create customized libraries used in the simulator. The structure of the plant control is as follows: the stoichiometric oxygen excess ratio is regulated by manipulating the compressor power, the equilibrium of the anode-cathode pressures is achieved by tracking the anode pressure with hydrogen flow manipulation; the oxygen and hydrogen temperatures are regulated in the heat exchangers, and the gas humidity control is obtained with a simplified model of the humidifier. The control scheme performance is evaluated for load changes, perturbations and parametric variations, introducing a growing current profile covering a large span of power, and a current profile derived from a standard driving speed cycle. The impact of the control scheme is advantageous, since the control objectives are accomplished and the PEMFC tolerates reasonably membrane damage that can produce active surface reduction. The simulation analysis aids to identify the safe Voltage-Current region, where the compressor works with mechanical stability.
