electrolysis Bayesian Network
Description
Safety analysis of proton exchange membrane water electrolysis system.
Format
A discrete Bayesian network to analyze evolving hazard scenarios, such as gas permeation/crossover during proton exchange membrane water electrolysis based on fluid dynamics and electrochemistry of electrolysis. Probabilities were given within the referenced paper. The vertices are:
- C
Operating current density (High, Low);
- F
Formation of hazardous H2/O2 gas mixture (Yes, No);
- FPR
Formation of peroxide radicals which can cause membrane degradation (Yes, No);
- GP
Gas permeation (Yes, No);
- GRE
Gas recombiner employed (Yes, No);
- H
Relative humidity (High, Low);
- HCF
Hazardous condition formation (Yes, No);
- HOR
H2 and O2 recombination at catalyst/membrane surface (Yes, No);
- IOA
Inhibiting oxygen accumulation (Yes, No);
- IRF
Inhibiting reaching flammability range (Yes, No);
- P
Operating pressure (High, Low);
- RGP
Reduction in gas purity (Yes, No);
- SBT
Surface/bulk treatments of the polymeric membrane (Yes, No);
- SMT
Sufficient membrane thickness (Yes, No);
- T
Operating temperature (High, Low);
- V
Operating cell voltage (High, Low);
Value
An object of class bn.fit
