A combined methanol autothermal steam reforming and PEM fuel cell pilot plant unit: Experimental and simulation studies

Optimal operability by design in a methanol reforming-PEM fuel cell autonomous power system

“…The non-linear steady-state model that fully describes the operating features of the autonomous power system has been reported in detail in [4]. However, for clarity the main model features are briefly outlined below.…”

“…Integrated systems for hydrogen production and subsequent power generation based on methanol have been studied extensively at a pilot plant scale level [4,20,21]. The design of such process flowsheets and the selection of the employed control structure are usually based on heuristics without a systematic investigation of the impact that complex interaction patterns have on the system performance under real operating conditions.…”

“…[18,19] for the systematic evaluation of the steady-state performance of two candidate flowsheet configurations and alternative control structures in order to satisfy the control objectives under the presence of multiple, simultaneous disturbances and model parameter variations. The case study system involves an integrated pilot plant methanol reforming e PEM fuel cell system as presented in [4]. The proposed framework employs non-linear process models that enable the calculation of the optimal steady-state behavior of the process system for constant design parameters (e.g.…”

Heat integration, energy efficiency, saving and security

“…The [26]. They reposted that an integrated system for hydrogen production via autothermal steam reforming of methanol and consequent power generation in a PEM fuel cell has been developed and operated at CPERI The pilot plant comprises an autothermal reforming reactor to produce hydrogen, a preferential oxidation reactor to reduce CO concentration below 50 ppm and a PEM fuel cell for power generation.…”

Experimental Characterization of the Poisoning Effects of Methanol-Based Reformate Impurities on a PBI-Based High Temperature PEM Fuel Cell

“…The methanol reforming temperature can further be reduced to around 200 °C, comparable to the operating temperatures of an HT-PEMFC, with good conversion efficiencies and low CO contents, but lower hydrogen yield [6]. This is desirable as it opens new opportunities, making methanol increasingly proposed for on-board reforming to hydrogen and carbon dioxide for indirect methanol fuel cells, including HT-PEMFC [6][7][8].…”
