Porous Titanium in Next-Generation PEMFCs

Porous titanium has found a wide variety of unique and important applications including filtration, separation, catalyst supporting, gas absorbing, gas sparging, current collection, and medical implantation.

Manufacture process for porous titanium

Raw titanium powder preparation—Cold isostatic pressing or rolling—Sintering in high temperature & vacuum furnace-Machined to size-Assembled to filter if required

Liquid/gas diffusion layers (LGDLs) play a crucial role in electrochemical energy technology and hydrogen production, and are expected to simultaneously transport electrons, heat, and reactants/products with minimum voltage, current, thermal, interfacial, and fluidic losses.

Porous titanium exhibits excellent properties when it is used as the anode GDL, because of its unique three-dimensional strut structure promoting highly efficient catalytic reactions. Furthermore, it shows superior corrosion resistance with almost no thickness and weight changes in the accelerated corrosion test, as opposed to considerable reductions in the weight and thickness of the conventional GDL.

Porous Titanium provides a longer-term reliability and chemical stability, which can reduce the loss of Pt catalyst and, hence, the cost of PEMFCs.
