....I do agree with you
....I do agree with you Martin, in that the slightly increased battery capacity adds no extra complexity, and probably not that much extra weight or packaging issues. It was my fault that I did not clarify my comment, which I intended to convey that for many users of this type of system, they may mostly be using their vehicle purely as a plug -in EV for routine short journeys, and may therefore perhaps hardly ever use said vehicle for long journeys to justify the extra expense for a more complex hydrogen fuel cell system ,and associated on board safe storage , which is rarely used, and in that case is mostly adding parasitic load . That said , one could make the same case for a fitted ICE range extender . I do suppose combining a hydrogen FC range extender to an EV , is a good method of introducing Fuel Cells to vehicle platforms, as hydrogen refuelling infrastructure can gradually develop , to address the paradox of which comes first, vehicles or associated refuelling infrastructure.
