Simulation at the Zemship

Objective:

Reducing the system costs and the total costs of ownership

• Reducing the installed fuel cell power at the ZemShip• Reducing system complexness• Rising system efficiency

Simulation parameters:

• Maximum fuel cell power is 30 kW (60%)• Only 2 system conditions max. power and half power• Fuel Cell System stops at a battery SOC higher than 95 %

The aim is a battery SOC equal to or higher then 90 % at the end of the day drive cycle.

Conclusion and development objectives

Conclusion:

1. Data sets out of the field demonstration systems are very important for further cost reduction processes

2. Developing a system power management what reduces the influence of the human factor the human factor can make cost reduction very successful or impossible

3. Field demonstration systems are the best way to design the right solution for serial Hydrogen Fuel Cell systems

Development Objectives:

1. Designing a standard one stack power module with 20 kW electrical power output2. Reducing system complexness and rising system efficiency 3. Defining a maximum of 3 Fuel Cell System conditions by using a standard Hybrid or

Triple Hybrid® concept
