What are current platinum loadings in Ballard fuel cell modules?
The loading on an 85kw fuel cell module – effectively two stacks – is around 75g (almost 2¼ oz) and slightly, although not significantly, less on the 8th-generation module. It is worth noting that 95 per cent of the platinum on a module is recycled when the time comes for the stack to be refurbished.
Is reducing platinum loadings over time key to achieving large scale adoption?
As I have said, driving down total life cycle costs of our products is critically important to achieving our goal of increasing megawatts shipped and for the industry as a whole to move towards scale. Platinum loadings, while of course a factor, are not a major consideration. I would expect some reduction in loadings over time, but we are not talking hugely significant amounts.
How does Ballard measure the effectiveness of the Platinum it uses?
At Ballard we know that higher power density (in kilowatt per litre or kW/L) is critical for vehicle integration, especially trucks. Only platinum-based fuel cell stacks can produce the level of 4kW/L we have achieved in our latest generation stack.
How does Ballard measure progress?
We look at megawatts of power shipped as a key measure; in 2019 over 100 megawatts of fuel cell products were shipped. Our ambition is to see this rise to 1,000 megawatts of power shipped, hopefully in the next three to five years. However, this will depend on market demand, which we believe is building for a number of reasons, not least the need to address climate change. The potential for the hydrogen economy to become a game changer in terms of decarbonisation of our economy and reducing emissions is firmly on the agenda around the globe.
