With hybrids being something of a stop-gap technology and electric cars currently limited by battery range, many are looking to hydrogen fuel cell powered vehicles as the answer to our motoring future.
However, as with conventional battery cars, fuel cell technology is still has a long development curve ahead of it and it is prohibitively expensive. Let's not even start on the lack on infrastructure.
Now GM and Honda have decided to hold hands to smooth the path ahead for this technology.
The collaboration expects to succeed by sharing expertise, economies of scale and common sourcing strategies in the aim of making the final products more affordable.
Both companies are leaders in fuel cell expertise, with more than 1200 filed patents between them.
