SOLID OXIDE fuel CELL DEGRADATION MODELING AND LIFETIME PREDICTION
SOLID OXIDE fuel CELL DEGRADATION MODELING AND LIFETIME PREDICTION
We investigate degradation mechanisms in solid oxide cells (SOCs) through integrated experimental and computational approaches. Our research combines SOC testing with 3D simulation models to understand local degradation phenomena and analyze accelerated degradation behavior at the microstructural level. This work aims to enhance SOC durability and enable the development of reliable, long-lasting energy conversion systems.

ammonia fueled fuel cell/electrolysis cell
ammonia fueled fuel cell/electrolysis cell
We explore ammonia-based energy systems using solid oxide cells (SOCs) and protonic ceramic cells (PCCs). Our research investigates nitridation phenomena and optimizes operational strategies for efficient ammonia utilization. For PCCs, we focus on reversible operation - enabling both ammonia synthesis through electrolysis and electricity generation from ammonia in fuel cell mode, establishing a complete ammonia-based energy cycle.

A novel system - a reversible solid oxide cell system with a thermocline-type thermal energy storage is proposed
The proposed system achieves a 27.5% improvement in efficiency over the solid oxide electrolysis stand-alone system.
The proposed system could achieve 0 kg-CO2-eq/kg-H2 of greenhouse gas emission
The proposed system can reduce a hydrogen production cost from $5.15/kg-H2 to $3.03/kg-H2.

Engine operation in the hybrid system is experimentally analysed for the first time.
HCCI engine is experimented while varying the operating conditions of the system.
HCCI engine yields a significant amount of power while emitting very low NOx emission.
It has been found how each system control parameter affects HCCI engine operation.
System operating conditions enabling successful HCCI engine operation are identified.

System operation is analysed by combining experimental results and simulation models.
SOFC should utilize anode inlet gas with low external reforming rate and temperature.
Pressure pulsation caused by the engine is insignificant for the SOFC operation.
Operational design point is determined considering performance and stability.
59% efficiency and near-zero pollutant emissions are achieved at the design point.

Excessive engine heat losses were analysed to be caused by unusual gas composition.
The ‘composition-considered Woschni’ heat transfer correlation was newly proposed.
To validate the correlation, experiments and simulations of the engine were conducted.
The new correlation showed much improved predictivity for engine performance.
The correlation can also be used to simulate engines using other unusual fuels.
