In this study, a three-dimensional numerical simulation of solid oxide fuel cell (SOFC) with dimensions 6 cm × on the anode side and 5 cathode (active area) was conducted to determine performance characteristics electrodes. The each SOFC unit were investigated through simulations. 3.5a COMSOL Multiphysics software used solve model. effects operating conditions, concentration, electrode porosity electrochemical electrodes examined. addition, an experiment investigate at 600, 700, 750 °C....
Anode-supported cells are prepared by a sequence of hot pressing and co-sintering processes for solid oxide fuel cell (SOFC) applications. Commercially available porous anode tape (NiO/YSZ = 50 wt %/50 %), 30 %/70 YSZ used as the substrate, functional layer, electrolyte respectively. After pressing, stacked layers then sintered at different temperatures (1250 °C, 1350 1400 °C 1450 °C) 5 h in air. Different compressive loads applied during sintering process. An (La,Sr)MnO3 (LSM) paste is...
A reversible solid oxide fuel cell (RSOFC) is one system, which capable of carrying out energy storage and power generation. In the electrolysis mode, an RSOFC acts as (SOEC), producing hydrogen (from water). a (SOFC), generating electricity by electrochemical combination with air. This study addresses fabrication its key component- electrode-supported that uses different oxygen electrodes (La0.8Sr0.2MnO3-5= LSM, La0.6Sr0.4Co0.2Fe0.8O3 = LSCF) within operation under SOFC SOEC modes. The...
Commercially available tapes (anode, electrolyte) and paste (cathode) were choosen to prepare anode-supported cells for solid oxide fuel cell applications. For both or electrolyte-supported cells, the anode needs pretreatment reduce NiO/YSZ Ni/YSZ increase its conductivity as well catalytic characteristics. In this study, effects of different pretreatments (open-circuit, closed-circuit) on cathode anodes SOFC performance are investigated. To investigate influence closed-circuit alone, a Pt...
Experiments were carried out to investigate the pressure drop and heat transfer behaviors of a microchannel condenser. The effects gravity on condensation steam in microchannels investigated for both horizontal vertical cases. For experimental results, condenser is lower than microchannels. In case microchannel, as mass flow rate increases from 0.01 g·s−1 0.06 g·s−1, 1.5 kPa 50 kPa, respectively. While 2.0 44 This clearly indicates that gravitational acceleration affects drop. obtained...
Using energy efficiently and reducing environmental pollution caused by consumption are becoming increasingly important. In this study, a two-dimensional (2D) solid oxide fuel cell (SOFC) stack configuration was designed to be operated with six cells. This design could potentially applied in thermal power plants developing countries where waste heat is more plentiful; the 2D six-cell an elementary module, such modules easily placed contact hot walls recovery required. report, design,...
Cold Thermal Energy Storage (CTES) is a technology with high potential for different cooling applications. Many previous works have investigated energy efficiency of cold units by applying CTES systems using phase change materials (PCMs). Phase (PCMs) are generally regarded as promising material storing thermal energy. This work presents an experimental study on storage application. The process phase-change based the following chemicals: water, propylene glycol...
This paper presented the results of improvement on Coefficient Performance (COP) split air- conditioner which has capacity 9000 Btu/h. uses R410A as refrigerant. COP is improved by using an innovative separated- vapor device (flash chamber) in system. The system designed to operate two cases. first case, saturated mixture liquid- refrigerant at low pressure passes through expansion valve (using tube) and enters flash chamber. second case that it directly evaporator. Both cases were...
Developing a cold thermal energy storage (CTES) technology is one of the most effective methods to solve shortage and environmental pollution all over world. The current study deals with modelling simulation tank consisting an polyvinyl chloride pipe (PVC) heat exchanger partially filled phase change material (PCM). Water, as transfer fluid (HTF), flows through inner tubes outer while propylene glycol fills. This paper focuses on studying effect velocity characteristics efficiency in system...
