文摘
- •
FIB and ultramicrotomy Polymer Electrolyte Membrane Fuel cell samples studied.
- •
Samples analyzed by transmission electron microscopy and soft X-ray microscopy.
- •
FIB caused amorphization of carbon support and destroyed ionomer (mass loss).
- •
Microtoming preserved chemistry; embedding media penetrated into electrode pores.
