Goretex in Fuel Cells?

In the category of “You aren’t going to believe this” is a story that was just sent to me by a reader. In a breakthrough being hailed as one of the biggest in 20 years of fuel cell technology, researchers at Monash University have replaced platinum in fuel cells with Goretex:

Monash fuels the next generation of hybrid cars

Monash University scientists have revolutionised the design of fuel cells used in the latest generation of hybrid cars which could make the vehicles more reliable and cheaper to build. The breakthrough, published today in the journal Science, revolves around the design of a fuel cell in which a specially-coated form of popular hi tech outdoor and sporting clothing material Goretex® is the key component.

The team of Monash scientists have designed and tested an air-electrode, where a fine layer – just 0.4 of a micron thick, or about 100 times thinner than a human hair – of highly conductive plastic is deposited on the breathable fabric. The conductive plastic acts as both the fuel cell electrode and catalyst.

Monash University’s Dr Bjorn Winther-Jensen said just as Goretex® had revolutionised the outdoor clothing industry, it could hold similar promise for motorists.

“The same way as waste vapour is drawn out of this material to make hikers more comfortable to less prone to hypothermia, so it is able to ‘breathe’ oxygen into our fuel cell and into contact with the conductive plastic,” Dr Winter-Jensen said.

Monash University’s Professor Doug MacFarlane from the Australian Centre for Electromaterials Science (ACES) said the discovery was probably the most important development in fuel cell technology in the last 20 years.

“The benefits for the motoring industry and for motorists are that the new design removes the need for platinum, which acts as the catalyst and is currently central to the manufacturing process,” Professor MacFarlane said.

“Our reliance on platinum is making the likelihood of using fuel cells in everyday passenger cars, increasingly improbable.

“The cost of the platinum component alone of current fuel cells for a small car with a 100kW electric engine is more than the total cost of an 100kW gasoline engine. Also current annual world production of platinum is only sufficient for about 3 million 100kW vehicles, less than one-twentieth of the current annual global production of vehicles.”

The new design fuel cell has been tested for periods of up to 1500 hours continuously using hydrogen as the fuel source.

Professor Maria Forsyth, Director of ACES at Monash said testing has shown no sign of material degradation or deterioration in performance. The tests also confirmed that oxygen conversion rates are comparable with platinum–catalysed electrodes of the same geometry and found electrodes are not poisoned by carbon monoxide the way platinum is.

“The small amounts of carbon monoxide that are always present in exhausts from petrol engines are a real problem for fuel cells because the platinum catalyst is slowly poisoned, eventually destroying the cell, “Professor Forsyth said.

“The important point to stress is that the team has come up with an alternative fuel cell design that is more economical, more easily sourced, outlasts platinum cells and is just as effective.”

Unbelievable.

  1. That is very nice, but if Monash is not cheaper to make and easier to handle than hydrogen. This is a dead end and irrelevancy.

  17. Chalk one up for Monash. Hope they get some licensing income, because the rumor is they just lost serious amounts of dough on American mortgage securities 😉

    Seriously, I’ve no doubt this is good work, but there’s a long way from the pages of Science to a commercial product, and there’s a very high failure rate along the way.

  25. Thanks for linking to this, RR.

    It is a great reminder that technology is the solution to our energy challenges, and that technological advances can (& do) surprise us all.

    Goretex may eventually turn out not to be the solution for fuel cells. But if enough human beings are encouraged to be inventive, we will eventually find energy supply technologies which are better & cheaper than fossil fuels.

    The issue is to get politicians to stop subsidizing currently-fashionable losers, which freezes technology and discourages breakthroughs. Instead, politicans should start promoting innovation.

  33. This article sort of changed my concept of a ‘wetted’ fuel cell. I thought the membranes worked better when wet, but can believe a gaseous phase electode promotes better mixing, and could aid in possible electrode fowling problems encountered, when experimenting with using short hydrocarbons as the fuel. I never believed Gore Tex is actually water proof, but I just sweat a lot. Is there any more info, diagrams, etc.

  42. Both fuel-cell technology for power generation and metal-air batteries for energy storage require an efficient electrode for O2 reduction. Such air electrodes are usually a Pt catalyst embedded in a porous carbon electrode.
