How the Fuel Cell works

HV-Battery

Connected with the Gumpert Power Cell (GPC) the high-voltage battery is providing extra power when the vehicle needs temporally more then the average power
and up to 100%, e.g. at acceleration or at gradients. The Gumpert concept is always based on an Battery-Electric-Vehicle (BEV) but requires only a fraction of the battery storage.
The battery is working bi-directional. It spends power when necessary and will be recharged by the GPC when it is drained.

Gumpert Power Cell

The GPC is a part of the powertrain in an electrical vehicle.
It is converting methanol into electricity. The fuel cell’s power class is depending on the vehicle category and the use case.
It is scalable and designed to produce the average performance of the vehicle. That means the fuel cell has a chosen size to
produce around 20-30% of the maximum power of the electrical engines. This enables the GPC to deliver the required power to drive
and lower costs and weight at the same time.

Methanol Tank

The fuel tank contains the methanol – refined hydrogen. Having hydrogen bounded in methanol is the most
energy-dense method to store it, compared to other hydrogen storing concepts. The fuel system is pressureless
and has ambient temperature. This keyfacts allows a simple and cost efficient design, similar to common gasoline tanks.

Using green methanol, the Gumpert Power Cell (GPC) provides electric vehicles with CO2-neutral energy. In a first step, green methanol is split into hydrogen and CO2 using an upstream reforming process. Next, the hydrogen is then transformed via a power cell into electricity. Depending on the operating condition, the electricity is then used to either power the electric motor to move the vehicle or charge an integrated backup battery. The size of the GPC is designed to continuously provide the average performance of a given vehicle and counterbalance peaks in performance of the electric powertrain and the backup battery. With this approach, a CO2-neutral electrical transportation is possible without relinquishing an urgently needed long-distance range or rapid refueling ability. Therefore, we are convinced that as a system supplier of the GPC, Gumpert Automobile will make a crucial contribution to the decarbonization of the transport industry.
