o One per project team o Promote sharing of ideas Grading, Incentives/Competition o Grades: Participation: 50%, Final Report: 25%, Final presentation: 25% Deliverables o Prototype, Report, Presentations o Prototype: Not necessarily complete, comprehensive/functional Can be virtual Materials Brainstorming Good Design Project Ideas Venture: Mechanical Engineering Vignette o Fuel Cell Technology Hydrogen fuel channeled through field flow plates to anode on one side of fuel cell, oxidant channeled to cathode on other side of cell Anode, platinum catalyst causes the hydrogen to split into positive hydrogen ions/negatively charged electrons Polymer electrolyte membrane allows only positively charged ions to pass through it to cathode; negatively charged electrons travel along external circuit to cathode, creating electrical current At cathode, electrons and positively charged hydrogen ions combine with oxygen to form water, which flows out of cell o Challenges Costs: engineers find another benefit that might offset cost of fuel cells to user Water/Air Management Temperature management Durability Safety Hydrogen economy/energy requirements o Applications Base load power plants Electric/Hydrid vehicles Auxiliary power Off-grid power supply Portable charging docks for small electics Smartphones with high power of consumption due to large displays/additional features
