Technology from American manufacturing firm W.L Gore and Associates has received a prestigious award from Toyota Motor Corporation for its contribution and value in the 2021 hydrogen-powered Mirai.
W.L Gore’s Gore-Select membrane technology received Toyota’s Project Award in the Technology Section, following increased performance and integration into the new Mirai.
Toyota incorporated the Gore-Select Membrane as its PEM (proton exchange membrane) – the core material of its fuel cell stack.
The membrane now helps deliver the second-generation of Mirai with a greater level of performance. Toyota reports 128kW (174 PS) of maximum fuel cell output with fuel efficiency of 152km/kg, translating to a cruise range of 850km.
Shinichi Nishimura, Gore Fuel Cell Technologies Global Product Specialist, said, “The science behind our unique reinforcement layer is a core technology Gore has cultivated for many years.”
“Applying this technology to the Gore-Select Membrane enables impressive improvements in the fuel cell’s stack size, performance and cost.”
Nishimura added, “We were very excited to bring this advanced technology to our partners at Toyota, and very honoured to be the recipients of their Project Award.”
To improve the second-generation Mirai, Gore-Select advanced the membrane technology increasing its overall performance.
It now features a 30% reduction in thickness with gas permeability and improved fuel efficiency in addition to a unique reinforcement layer that significantly improves the membrane’s mechanical durability.
This means that the new fuel cell electric vehicle (FCEV) has a more compact, higher-performance fuel cell stack with better durability as well as boasting a lower system cost.
