They don't? When the Toyota hydrogen cars were introduced here around 2015, one of the issues were that a full tank of gas would dilute through the tank walls within a week. From the marketing material of the latest Toyota Mirai, it seems that they still use Hydrogen stored in gas form, boasting improvements in a 3-layer tank that is tested for 235% of the pressure that the gas is stored at, compared to 150% for regular gas containers.

They don't. They use hydrogen fuel cells to generate electric power.

Yeah and what does that have to do with the Hydrogen being stored in gas form? The fuel cell converts it, it isn't a storage mechanism. Hydrogen has a boiling point of -253C, are you saying that Hydrogen powered cars are fitted with a power hungry cryo chamber to cool down the fuel to a liquid form?

They are not storing the hydrogen at atmospheric pressure
