“…However, as a result of the relatively thick electrolyte, ionic resistance across the electrolyte is large for this design. The best performing SOFC cells of recent design are the anode-supported cells in which the mechanical strength is provided by a thick (~ 1.5 mm) layer of anode (usually nickel-YSZ cermet) material [19]. Thin electrolyte and cathode layers are deposited on the anode material by screen printing or other techniques.…”

“…The steam/ hydrogen electrodes (cathode in the electrolysis mode) are also graded, with a nickelzirconia cermet layer (~13 ȝm) immediately adjacent to the electrolyte and a pure nickel outer Planar stacks can also be assembled using electrode-supported cells. Advanced technology SOFC stacks based on anode-supported cell technology have been developed by several manufacturers under the Solid-State Energy Conversion Alliance (SECA) [19] program. For example, Versa Power (partnered with Fuel Cell Energy) has developed anode-supported planar cells with dimensions as large as 33 × 33 cm.…”

“…Performance degradation is also an important issue for solid-oxide fuel cells (SOFCs) and addressing this issue has been a major focus of both the US DOE SECA program [19] and the European Real-SOFC program [26]. Significant progress has been made in identifying and mitigating degradation mechanisms in SOFCs.…”

The Department of Energy, Office of Nuclear Energy, has requested that a Hydrogen Technology Down-Selection be performed to identify the hydrogen production technology that has the best potential for timely commercial demonstration and for ultimate deployment with the Next Generation Nuclear Plant (NGNP). An Independent Review Team (IRT) has been assembled to execute the down-selection. This report has been prepared to provide the members of the Independent Review Team with detailed background information on the High Temperature Electrolysis (HTE) process, hardware, and state of the art. The Idaho National Laboratory has been serving as the lead lab for HTE research and development under the Nuclear Hydrogen Initiative. The INL HTE program has included small-scale experiments, detailed computational modeling, system modeling, and technology demonstration. Aspects of all of these activities are included in this report. In terms of technology demonstration, the INL successfully completed a 1000-hour test of the HTE Integrated Laboratory Scale (ILS) technology demonstration experiment during the fall of 2008. The HTE ILS achieved a hydrogen production rate in excess of 5.7 Nm 3 /hr, with a power consumption of 18 kW. This hydrogen production rate is far larger than has been demonstrated by any of the thermochemical or hybrid processes to date.This report was prepared in April-May 2009 specifically for the IRT, which at the end of its evaluation in July 2009, recommended that:DOE-NE should focus on the continued development of HTSE [High Temperature Steam Electrolysis] as the leading candidate for integration with NGNP in 2021. This conclusion is based upon the IRT judgment that HTSE has the highest probability of meeting the down-selection criteria described in the report, including efficient production of hydrogen at NGNP conditions.

a b s t r a c tWhile adding distributed energy resources (DER) to a distribution circuit will affect numerous aspects of operation, bus voltage is a critical aspect that must be maintained within acceptable limits. It is therefore critical to: (1) quantify how DER installation will affect the voltage, (2) visualize the voltage change, and (3) predict the voltage change of the alternatives within the DER operational space. These three goals are achieved through the development of a simple voltage change potential (VCP) visualization method that can be determined using the basic characteristics of an inverter-based DER installation. The VCP results compare favorably with equivalent complete non-linear Matlab/Simulink TM models of DER implementation in distribution circuits at a fraction of the computational time. Calculation of VCP also enables a new control method that uses circuit information and simple equations to provide situationdependent and optimal voltage regulation.
