ADVANCED MEMBRANE FOR HD TRUCKS
DOE PROJECT II
FY '20 DOE ADVANCED MEMBRANE PROJECT:
* Objectives:
■
MEA based on reinforced PFSA membrane that
meets performance/durability targets at ≥ 95°C
Reduce radical scavenger mobility
Prevent ionomer radical attack
Develop & validate HD-specific membrane AST in
conjunction with DOE FC-PAD
❖ Partner:
Chemours™
Chemours
New membrane chemistry and architecture
with an immobilized radical scavenger
High(er) Temp. Stability - develop
ionomer/reinforcement architecture
optimizing membrane thickness for
reduced gas crossover
OVERALL MEA DEVELOPMENT AT NIKOLA:
Design and Develop MEAS optimized for
High efficiency
Cost
Durability under HD Drive Cycles
.
Develop Accelerated Stress Tests (ASTs)
specific to HD truck operating
conditions
=
Predict fuel cell stack failure modes
Develop mitigation strategies
Materials
Appropriate control strategies
