An Enzymatic Biofuel Cell (EBFC) converts the chemical energy in biological fuels into electricity. In this work, we optimize the performance of the Carbon-Micro Electro Mechanical system in an EBFC by using COMSOL Multiphysics. With a simple model, we realized that most of the glucose ... 詳細を見る
Aluminum alloys in near-neutral, mildly aggressive solutions, undergo damage accumulation during corrosion, mostly due to the presence of micrometer-sized constituent intermetallic particles (IMP) that create a microstructural discontinuity at which localized corrosion occurs. The ... 詳細を見る
The corrosion at cut-made edges is significant due to the anode to cathode surface ratio in this region. The major problems are the risks of red rust appearance at the exposed steel surface, and the risks of paint delamination in case of insufficient corrosion protection. The work ... 詳細を見る
Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour ... 詳細を見る
The present work focuses on modeling a new experimental technique: Scanning Electro-chemical Potential Microscopy (SECPM), which is used to probe the potential profile of the electric double layer (EDL). We used an electrostatic approach to compute the EDL potential measured within the ... 詳細を見る
Corrosion of metals in confined zones is a big industrial problem. The electrochemistry of such localized corrosion processes is complicated by the impact of the corrosion processes on the composition of the local solution. In the present problem, local interaction with the atmosphere ... 詳細を見る
Progress in coating technology has allowed for the development of free-chromate corrosion inhibitors, which are able to smartly migrate when required. In order to support the coating design, we propose a hybrid mathematical model to study the inhibitor's release by taking into account ... 詳細を見る
The steady-state non-equilibrium distributions of two species of mono-valent ions around a charged nanofluidic channel have been examined. Large reservoirs were placed on either side of the nanoscale channel to simulate bulk concentration of ions in a fluid. Results from COMSOL ... 詳細を見る
Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics® is used to describe an intermediate temperature solid oxide fuel ... 詳細を見る
This computational implementation presents a new strategy of coupling two 3D models to satisfy the requirements of the comprehensive model of a unitary Proton Exchange Membrane fuel cell, including its internal geometries and constitutive materials, as well as distinct physical and ... 詳細を見る
