LNC's take up of the AFC option has certainly stirred the possums in the AFC camp. There is a very good overseas stock forum which discusses AFC's prospects. The fact that it has jumped around 40% in a week since announcements of a AFC fuelled power station proposal and then LNC's buy in hasn't hurt.
I've attached a relevant observation from a person who visited the AFC plant on a recent open day. .. A long read and a bit ramblay but very interesting from our point of view as partners in this technology and having the opportunity to let it loose on the power generation industry in Australia and around the world.
Cheers

..I asked when we can expect the order from Linc which I wasn’t expecting an answer to as it would be price sensitive. He skilfully turned it around and told the tale of how Peter Bond had started out as a truck driver driving coal between 2 mines who took a punt on the land between the 2 mines having coal under it as well. Turns out he was right and made £100 million dollars in the process! Then acquiring a majority stake in Linc Energy with the proceeds. He is a man who does not like to mess about according to Howard, one of the richest men in Australia and quite hell bent on becoming THE richest man in Australia, if LINC pans out then he may just do it.
Basically the upshot is they want 300MW of capability and they want it now! I also asked whey the alpha test cell had not been shipped to Chinchilla yet to which he replied they are waiting for the infrastructure to be put in at Lincs end. The cell is ready to be shipped they just don’t want it sitting idle in a shed in the desert. Also if any technical improvements are made at AFC’s end they can be implemented before shipping. Peter Bond has recently visited AFC and is as keen as ever to start implementing the technology asap.
It was then our turn to have a trip around the lab with GL (Gene Lewis), this is the part of the trip I enjoyed most and found the most insightful into AFC’s business. He started off by explaining who he was and what his background was. A materials engineer working with ceramics and fuel cells for 15 years. He was one of the key engineers at Ceres power for many years, when asked why he left he said it was because he thought he had taken it as far as he could and thought they would struggle to reach commercial production due to the complexity and cost of manufacturing.
After leaving on good terms he had no plans to continue work in the fuel cells field but heard about AFC by chance and after touring the facility quickly realised ‘he had been going about this the wrong way’ (Howard’s words) GL explained that whereas SOFC and PEM fuel cell tech has had millions if not billions of money poured into it by companies all over the world no-one had really looked at alkaline fuel cells since the 60’s seeing them as a dead end and defunct technology.
He explained that 10 even 5 years ago they could not do they stuff they are doing today. Advancements in manufacturing processes and low cost materials for parts and electrodes meant that what once was a very expensive field requiring capital intensive materials such as platinum was now an open field for technological advancement. Once deemed only suitable for projects where money didn’t matter (space travel), alkaline fuel cells have a new wind in their sails.
As AFC is the ONLY company worldwide to his knowledge that is currently pursuing Alkaline technology they own the book, an ‘IP land grab’ was the phrase he used. As all previous patents for this tech are now so old it meant they can basically brand it AFC and with the advancements they are making then it will be difficult for competitors to catch up, though they expect others to join the race.
The main problem with SOFC is the heat and pressure on the materials used in their construction, with the low temp AFC cell these problems don’t exist. GL was smiling as he held up a simple component made from mass producible ABS plastic and rubber o rings, which he then just pushed into a cell stack. Howard said GL’s favorite word was cheap and he wasn’t wrong.
Nearly every aspect of the afc cell is designed and made from mass producible cheap materials and uses off the shelf parts like pumps and joints. No expensive sealing and specialist parts or processes are required. The electrodes are made by screen printing, again a tried and tested manufacturing process. When he demonstrated how a cell was assembled (using an older model) it couldn’t have been simpler to assemble, very few parts made of plastic mainly. It reminded me of something you might get from a toy model shop, a 5 year old could build one!
And as if it needed to be any better a vast majority of the finished fuel cell stack is re-usable so when it does need replacing it can be reconditioned, and not only that it can be reconditioned with the latest model. Justin likened the process to taking your car in for a service, going in with a 1.4 engine and coming out with a 2 litre!
Again and again GL kept reiterating the simple nature of the construction. He also hinted at the leaps and bounds the design is coming along, making it even simpler with fewer parts and increasing the efficiency (volumetric density) of the cells. He compared the test process for new materials to that of SOFC from his days at CERES as what takes them weeks to build and approve for testing they can do in a morning thus enabling rapid advancement. He had just returned from holiday and said it had taken 4 days to get back up to speed with the developments the team had made, such is the speed they can work. The Small focussed team with no red tape and a very short turn around time for testing new ideas is allowing AFC to pull further and further into the lead with this technology.
We then were shown the test bed where 2 fuel cells sat hooked up to monitoring equipment, albeit their were no actual cells on the units it was clear to see where they went. GL explained the set up and what each of the components did and showed us the manifold ‘spine’ of the cell, which looked like a rat maze (again made from vacuum formed abs!). Here I asked him about the 50kw cell and liked what I heard, his response was ‘why 50kw?’
The original intention was to make these units produce 50kw then stack then up each finished unit been made from 4 x 12.5kw cell stacks. He then pointed out that to do that you would need individual parts for each 50kw unit ie x many pumps, x many control valves, x many filters etc. He then went onto explain the concept of the scalable cell that they now have their eyes set on, as in the diagrams of the super green power station we have seen this will consist of numerous cells (10kw according to Howard) which are stacked up in rows both horizontally and vertically, each one bolted onto the next all sharing the common parts such as electrolyte pumps and hydrogen delivery.
Thus the concept of the 50kw cell is old hat, say hello megawatts !! I’m sure the 50kw cell will have its place but this scalable power station is where the future lies for AFC in my opinion. This is where the engineering expertise of WSL and Air products will come in to make it a reality and thus make us all quite a lot of dosh in the process. A fact GL was not shy about saying. They are creating a product to make money not indulge science!
