High Temperature Electrolysis (HTE)
Project Summary
| Full Title: |
High Temperature Electrolysis (HTE) |
| Project ID: |
159 |
| Principal Investigator: |
Steve Herring |
| Brief Description: |
A three-dimensional computational fluid dynamics (CFD) model was created to model high-temperature steam electrolysis in a planar solid oxide electrolysis cell (SOEC). A solid-oxide fuel cell model adds the electrochemical reactions and loss mechanisms and computation of the electric field throughout the cell. |
| Keywords: |
Solid oxide fuel cell; solid oxide elctrolysis cell; nuclear; model |
Purpose
Assess the performance of solid-oxide cells operating in the steam electrolysis mode for hydrogen production over a temperature range of 800 to 900ºC.

Project Description

Model |
| Category: |
Hydrogen Fuel Pathways |
| Methodology/Approach: |
Mass, momentum, energy, and species conservation and transport are provided via the core features of the commercial CFD code FLUENT. A solid-oxide fuel cell (SOFC) model adds the electrochemical reactions and loss mechanisms and computation of the electric field throughout the cell. The FLUENT SOFC user-defined subroutine was modified for this work to allow for operation in the SOEC mode. |
| Outputs: |
Model results provide detailed profiles of temperature, Nernst potential, operating potential, anode-side gas composition, cathode-side gas composition, current density and hydrogen production over a range of stack operating conditions. |
